I've been to the Crown Paradise Club a couple times, loved it both times. Has a cool wrap around design for the rooms so there are a TON of ocean view rooms. Has wicked food and beach, 3 pools to lounge around and drink like a fish, and not a ton of sales people trying to sell you shit...no I don't want your god damn time share thank you very much.
And I agree with everyone here who's said Xel-ha is a must, because it is, unreal time there.
