I've always thought the emphasis at Capricorn was more on the restaurant than the cabanas. The co-owner built the cabanas, and I think they are fine, but it's definitely not a resort atmosphere.
From Capricorn, you would normally take a water taxi to town. You can drive a golf cart, crossing over the little hand-pulled ferry, but the ferry doesn't run after dark.
There's not too much nearby -- just Captain Morgan's, a palapa bar, Sweet Basil's.
