Yes agree with Hiljil the prices have alot to do with the gulf beach access.
We stayed once in a complex around Bradenton, Sarasota. However it was a real pain getting to the beach, lots of traffic there and back. Thats why we pump for rentals on Long Boat Key these days and plan our exit off that barrier island when we know traffic if not too bad but prices are very high though.
Often you can pick up a wonderful large rental villa with loads of room and a huge pool on really nice complexes away from the beach and if the price is right, then I personally think thats a good idea. However to others (like my family
the beach is more important).
