Hi and welcome to Cruise @ddicts!
I have never sailed Oasis but have a booking for next September (one of her very rare cruises in the Mediterranean sea).
I heard that it's a good idea to book the shows in advance. The same also for the specialty restaurants.
About driving down to FL, I can't give any comments on that as I live in Europe, but I would not mind doing that as it would mean I got to se a bit more of the US! It would probably take me more than a week though, as I would make a lot of stops on the way down as there is so much to see (and problaby many Cruise @ddicts to visit too)! :doubleup:
