We stay at Seawatch every year. This is if you like a "hoppin'" atmosphere. There's a DJ at poolside twice a week, you got the poolside tiki bar, craft activities for the kids, on-premises restaraunt and even at night you have people hanging out by the main pools.
Don't know about any of the others, but if you want a quiet, relaxing vacation week, Seawatch is probably not the one. If you do want to book a unit at Seawatch, try going through ebay, craigslist or VRBO for the best deal.
