We are going on the 4/3 Carnival Conquest to Jamaica, Grand Cayman and Cozumel. We have never been to Jamaica, but would love to go to Margaritaville, but were wondering about the prices. We heard that one drink cost $20. Has anyone been recently and could give us more information. We are going to Sunset Beach resort first, but wanted to stop in at Margaritaville on the way back. Any info would be appreciated. Thanks.
