A few years ago, must have visited 15+ gated communities in the central area of FL, north of Orlando and south of Ocala. As a starting point for comparison purposes, look at The Villages, which has a number of amenities, clubs, entertainment etc. Their web site has new as well as re-sale homes.

A number of these communities offer the package specials for a 1 to 3 day visit
An agent if your looking in the Mt Dora area which is also North of Orlando

Numerous choices in the state , depends upon your desires of gated, amenities , ocean or in-land, north or south of Orlando etc., etc.,
When relatives were into the selection process, ended up at The Villages, they rented for 2 months to gain personal experience, deciding on a life style etc as well as allowing time to visit a number of communities
I have vacationed in the Pensacola area......was great
