First off, congrats to your DD!
I would definitely, definitely, definitely recommend having a car while on the college program. While it is feasible to do it without a car, it can be quite depressing to not have one and be stuck to a bus schedule or begging rides off other people. Especially if you want to see more than Wal-Mart and Disney while in Florida.
Luckily I met a "special friend" early in the program and he let me take his car all the time (he wasn't a CP). Otherwise I would have gone crazy.
How long is your DD on the program for?
