BY CAR

FROM THE SOUTH:
Take I-95 North to exit 5, College Park. Get on Route 1 South. The University of Maryland will be 2 1/2 miles south on your right.

FROM WASHINGTON:
Take Rhode Island Ave North out of the city. Rhode Island Ave turns into U.S.1. Continue north until you see the University on your left.

The Quality Inn is perhaps 1/2 mile south of the University campus, at the third traffic light on Route 1 south of the campus. The address of the Quality Inn is 7200 Baltimore Boulevard, College Park MD, and its phone number is 301-864-5820.

BY TRAIN

Getting off at Union Station, you can take Metrorail to the College Park Station: from Union Station Metrorail, take a red line train (marked Wheaton or Silver Spring) to Fort Totten station; transfer to a green line train (marked Greenbelt), get off at College Park station. (You can also catch Metrorail at New Carrolton but the route to College Park is less efficient.)

COLLEGE PARK METRORAIL STATION

Alternately, you can catch a taxi at the main taxi stand for the station; this is on the east (busy) side of the station (do not cross under the MARC tracks). The taxi ride to the Quality Inn would now be 2-3 miles.

When classes are in session (Mon-Fri), the University of Maryland shuttle service runs from the station to campus about every 20 minutes, from 7:00 a.m. to 7:40 p.m. This shuttle is free for anyone. It leaves the station, crosses Route 1 to the University; about 100 yards after Route 1, on your right you will see a building with a grey slate dome. That is the math building. There is a stop at the roundabout just ahead at which you can exit the shuttle (and walk back to the math department).

BY AIR

CAVEAT:
--Metrorail's listed operating hours end at midnight. With the transfers, the metrorail trip from National can take an hour.
--Dollar figures below are a year or two old.

National Airport:
You can walk to a Metrorail station across the parking lots (or wait to take one of the frequent and free shuttles). Take Metrorail to the College Park station.
(Take a yellow line train marked Mt. Vernon Square, go to Gallery Place station; transfer to a red line train marked Fort Totten, go to Fort Totten station; transfer to Green line train marked Greenbelt, get out at College Park.) See the algorithm for College Park station above.

BWI (Baltimore-Washington International Airport):
Airport Connection ($16 to College Park)
This is a reasonable two-stage airport-to-doorstep service. A bus takes you to a satellite station not far from College Park, where smaller vehicles take passengers to their doorsteps. Sunday through Friday, the bus from the airport leaves every 90 minutes from 7 AM to 10 PM, then there is one last bus out at 11 PM; on Saturday the buses depart only every 2 and 1/2 hours, from 7:30 AM to 8 PM.

BWI Airport Limousine Service ($47 to College Park) The fee does not include driver's gratuity. (It also explicitly excludes parking fees, but you will not have these at the Quality Inn.) The driver will meet you at the airport gate and assist at baggage claim. You have to call in advance to make a reservation, 301-441-2345.

Taxi from BWI A taxi group (Blue Bird Cab Co., 301-864-7700) gave me the estimate "about $40" for a cab to the Quality Inn. The Limo Service above gave essentially the same estimate for a taxi (which competes with the limo) to College Park.

(more information: ground transportaiton desk at BWI: 410-859-7545)

Dulles Airport:
Take the Dulles Express shuttle from Dulles to the nearest Metrorail station, West Falls Church (approx. 20 minute trip).
(The one-way fare for the Dulles Express shuttle is $8, cash only. Shuttles leave the airport every 20-30 minutes, from 6AM to 10:30PM weekdays, from 7:30 AM to 10:30PM Sundays and holidays) Take Metrorail to College Park.
(Take the orange line train to Metro Center, transfer to a red line train marked Wheaton or Silver Spring; go to Fort Totten station, transfer to a green line train marked Greenbelt; exit at College Park.) (This takes about one hour and costs $2 or $3.15 depending on the hour.)
See the algorithm for College Park station above.

Alternately the Dulles taxi authority (703-661-8230) tells me that a taxicab direct from the airport to College Park will cost $50-55.

DRIVING TO THE CONFERENCE

To drive to the conference, for example come south from the Beltway on Route 1 as described above, passing Route 193 and several stop lights. At one light, on the right will be a McDonald's. Then you pass a Jerry's fast food place on your right. At the next light, turn right onto Campus Drive, entering the campus. If you continued straight on Campus Drive for 100-200 yards, you would be in front of the Math Building, which is four stories and supports a large gray slate dome. However, to park, continue as follows:
--on a weekend (or after 4PM)
Take the first right (after turning from Route 1), then take the first right (leaving the road for a parking area), and park.
--on a weekday
After turning off 1, continue straight until you hit the traffic circle, turn right there, take the next left into the parking garage and park (and pay).

Coming up Route 1 from the South (e.g. from the Quality Inn), you will pass a traffic light in front of the Quality Inn, a traffic light at a shopping center, another light with a book store on a corner, and two minor traffic lights. The next light has a left turn lane which you take to turn onto Campus Drive. This is the turn described above from the north. Now reduce to the previous algorithm for parking.

CHEZ BOYLE (Party, Fri. 7:30)

>From the Quality Inn:

Drive south on Route 1 to the very next traffic light (at Guilford), which has an Exxon station on the far right corner. Turn right. When this road ends (at the third stop sign), turn left. At the first serious intersection (the second stoplight), turn right, onto Adelphi. Almost immediately there is another stoplight--go straight through, continuing on Adelphi. Turn left at the next stoplight, onto Metzerott Road. Take the second left, onto 23rd Avenue. After 4 blocks, 23rd court hits 23rd Avenue from the left; opposite, on the right side, is the Boyles' driveway (the larger house, on the right side of the driveway, is the Boyles'). Park on the street (don't go up the driveway--not enough room). The total drive from the Quality Inn is roughly perhaps 4 miles.

>From I-95, coming south from Baltimore: exit onto 495 (the Beltway), going west toward Silver Spring and VA. Take the New Hampshire exit going south (New Hampshire is the first possible exit and the south exit is the second of the two exits onto New Hampshire). Take a left onto Adelphi (the second light). Take a right onto Metzerott (the second light). Take the second left (onto 23rd Avenue). Pick up the previous algorithm.
