Has anyone done this specific excursion? If so, please tell me about your experience with it as it's my 1st choice so far for my June cruise. Was the food at the included buffet good? What sort of things did they serve? Were any alcoholic drinks included? Were beach umbrellas provided for free? I pretty much plan to relax on a lounge chair with a protective umbrella, a tropical drinkin my hand, and my feet dangling in the ocean.
