There is a lot more in the Altamonte area than around UCF. Also, Altamonte has access to I-4 if that matters. Having said that, UCF would have quicker access from the airport by taking the Greenway.
I think that the R.I.s are both a little older at both locations, but they would be fine based on the outside. In terms of what's around UCF, it's just the usual chain restaurants (Applebees, etc.) whereas Altamonte would have all of these plus some other options. Both would be 10 -15 minutes from Winter Park, which would have really good dining options.
