UCLA has a ballroom dance club that holds swing dances about once per quarter, usually with a live band, Swing Inc. These usually have mostly students and staff of UCLA, with a few West Side locals. Go if you're nearby and want to meet some new people. Bring your own partner if you want to do anything advanced.
Parking is a little bit tricky now that there is so much construction going on. Only certain lots let you pay; the rest require a UCLA parking pass. Structures #2 and #8 are probably your best bets.
Kerckhoff Grand Salon is also a bit hard to find. Go to the main quad and head due East. After Ackerman union, the building on the right is Kerckhoff.
Keep going and make a right to go around the back. Go through the outdoor dining area, and you should start hearing the music. Check out this interactive campus map
for more details.
