Reservation

The table is usually provided by the university, so all you need to worry about is to reserve the table early enough. You might be able to reserve the table for the whole semester every two weeks, but usually the university puts restrictions on the frequency of recurrent reservations. So you might have to visit the reservation office once for every few Da'wah table reservations.

Locations

Go for crowded places. The library main entrance was excellent. The Student Union lobby was very good too.

Times

We tried 11:00AM to 2:00PM and 1:00PM-4:00PM and both were successful. So time doesn't seem to matter much. The lunch break is usually more active, i.e. 12:00-1:00PM.
