I can't speak for the SAAF, but Gatorland does offer a single day Photo Ticket that allows you in at 7:30am and out at 7:30pm. Price is $29.99 and is available online at our website. You can pre-purchase and bring a printout of the order to the Admissions gate for easy entry. I'd suggest coming to Gatorland first from West Palm, much shorter distance... and I have a feeling you won't want to leave as there is a LOT of action right now at Gatorland!
I don't have a suggestion for hotel/motel, but there are literally hundreds available in the area. I believe I heard the Quality Inn on 192 was nice for about $50 a night. I have a house... and am single, so I never use the hotels around here! :)
