Thought I would pipe in on Cypress Cove as well as my wife and I have stayed there 3 times (flying down to camp at end of February as well). While I know a bunch of people have been/are aware of how nice a club Cypress Cove is, thought I would put a plug in for their youth rates (under 35).
Under 35 gets $5 day fees (a steal) as well as premium pricing (~$27/night, includes your day fees for a couple) for tent camping in their rustic campsites (no electricity/water, but a bathhouse 100 ft. away). My wife and I always camp there as you can't beat the price and, even with the hassle of flying our tent, camping stove, coolers, etc. down there, is way too good of a deal.
Anyway, long winded way to say that I would definitely recommend checking this place out if you haven't. Easy to fly into Orlando, pick up a rental car, and head south.
