I ended up booking a trip over the weekend. The wife and I will be getting away without the kids in November. We ended up booking a swim out room at Sandals in Grenada. I've never stayed at a Sandals, but have always heard great things.
Never been to a Sandals, but took my family to Beaches (Sandals' family resorts) Turks & Caicos in February and it was head-and-shoulders above any all-inclusive I've ever been to. Mind you, you pay for that premium, but it's nice knowing all the restaurants are actually good (not "good for all inclusive") and you can order a Johnny Walker black label at the pool bar at 10am...
I'm sure you'll enjoy the trip.
