I believe the Cove is adults only, very nice place but very expensive even when room is comped. I like Royal Towers, smack dab in the middle. Close to the pool, beach, and casino.
Best bet for family of 10 is harbourside Villa's, its a bit of a walk and not right on the property but still close enough. Staff is awesome, don't believe any crap about them being rude. Nicest people I've met.
Here's video proof when I got caught filming by a security guard.

Here's a link to the harbourside options. Let me know if you have any other questions.
