Yacht Haven Marina
Great place to stay and the people are very nice. Centrally located and have grocery store right next door. The facility was clean and convertible. The one thing I would warn anyone who wants to stay here is if you have motion sickness the constant movement of the boat will cause you issues.

Skipjack Resort & Marina
Room was clean but could use a bit of updating. Staff was very nice but always busy so there was a wait to order a drink, close out a tab, or talk to someone at the front desk. Great location. Comfy bed. All needed kitchen equipment. Would stay there again.

Tropical Cottages
This operation was pretty solid, and the cabin was nice and clean. Parking is close to cabins, which made it easy for me to load/unload bags and scuba gear. Staff was friendly, and works hard at keeping the grounds spotless and full of life. Would recommend, and plan on going back.
