I like Jungle Jeanie's, also called Jungle by the Sea. It's south of the village, on the water. Pleasant cabanas, but no A/C. Hopkins Inn is another nice moderate place. Don't think they have A/C, but I may be wrong about that.
Another spot that's not bad and has A/C is Parrot Cove, which used to be called something else-Cove that doesn't come to mind at the moment. It's in the same area as Beaches & Dreams, south of Jaguar Reef. The rooms in the main building are smallish but moderately priced, and there's a pool. Fancier apartments are also available. Eating breakfast there earlier this year, I saw both a manatee and porpoises just off the beach.
Then of course you have the more upscale places. Hamanasi is the class of Hopkins, with Jaguar Reef and Hopkins Bay/Belizean Dreams condos also very good but not cheap.
