To get to the college, Route 2 exit 31B.
Travel north on Route 12 for 2.8 miles, then turn right over the bridge(this is a Y intersection at a light).
At the bottom of the bridge, turn right again, on Main Street.
Take the second left (before the Dunkin' Donuts) onto North Street.
The college is located three blocks up.
Once you get to Pearl Street (stop sign at intersection, with parking lots on either side of road) turn right and head up the hill.
Take the second left onto Ceader Street.
Take the second left into the parking lot and find a space. The second lot (on top of the hill is usually pretty empty)

In the map above, the pink lines are driving directions, the yellow are walking.
The pink circle is the reccomended parking lot, the yellow circle is Percival Hall.
To get to Percival Hall, walk to the parking lot entrance and head up the hill between the buildings.
Cross the street and there should be a small park directly in front of you. The building to your left is Percival Hall.
Enter from the street side and walk up the steps, the entrance to the theatre is through the doors in front of you and to your left. There should be people around to help you out, sell you tickets, etc.
I have talked to the designer, and she always designs a show from house center, about 10 rows back.
When you are ready to leave, Cedar, although it doesn't look it, is a two way street. Just follow the directions backwards and you should be all set.
