I have stayed at Seastar and love it. Great bar, great kitchen, excellent pool, excellent staff, near perfect management - Chris and Francine are exceptional. We'll be staying at Catcha Gardens this Holiday season for 10 nights. It comes highly recommended from a number of friends but I'll be happy to give you my personal review when we get back. Don't think you can go wrong with either but I think an easy comparison would be Seastar - more hoppin', Catcha Gardens - more laid back.
