Yes, no, and maybe.
Enrollment deposit is NOT refundable. I could be wrong, but I think that might be the case across the board in Florida.
Some people consider that $200 a reasonable sacrifice. We were gonna take it, but when we went on the tour (after acceptance, but before UF/FSU decisions), our daughter stopped us about 3/4 through the tour and said, “This is what I want. Let’s go to the store and get a sweatshirt.” (And she never looked back.)
Housing deposit IS refundable at UCF, provided you change your mind within a certain timeframe. I do not know about other schools.
However, if you miss the deadline to cancel, you could get hit with a $1,000 penalty. But you’d have to mess up pretty bad to get that penalty – the deadline is pretty late.
