I am in ACE 6.120; the map of ACE and its surroundings are here. The GPS co-ordinates are Longitude 30.287253, Latitude -97.736832.

If it's before 5:45pm, you should park in PG1 which you can find here. To get from PG1 to ACES, walk south on San Jacinto to 24th, west on 24th, ACE is on your left, about 200' up. (Rates: 3$ for 31-60 mins, $5 for 61-120 mins, $7 for the whole day after that, as of 3.12.03)

If it's after 5:45pm, parking on campus is open, except for a few marked spots.
