Been to South Seas, loved it
Try to get a ground floor beach "cottage" (half the lower floor of a 4 condo unit). Just about everything has a balcony or a screened porch that overlooks the Gulf, but the ground floor of the beach cottages are the only ones that let you walk straight off the porch and onto the beach, which sure beats having to schlep all the towels, beach chairs and float toys out the front door, down a hall or down stairs...and great for the kids 'cuz they can play in the sand while you sit on the porch over a drink and watch the absolutely spectacular sunset. The water is VERY shallow around Captiva...and every storm shifts the bottom...so you may find that a skiff is a better choice for boating than a sailboat if you don't know the waters.The restaurants at South Seas are ok...but there are better ones--that are less expensive too--outside the plantation. Don't miss the Bubble Room...the food is excellent, but it's the decor that makes the place.If you've never eaten fresh stone crab, you're in a for treat...'cuz winter is when it's in season. Order it cold, never hot...only tourists who don't know any better order it hot. They can only take one arm off the crab and have to throw the crab back...that arm has to be cooked immediately on the boat, then chilled...which means that restaurants have to re-heat it to serve it hot, and it isn't nearly as good. South Seas is a first class resort, but very relaxed and casual compared to others...for instance Longboat Key Club. You'll like it.
