i agree^^^ 1000%. the wife and i WILL eventually do a cruise, but every sandals trip we've been on has been awesome. the liquor is not 'top shelf', but it is absolut/jack daniels/jose cuervo/etc. which is totally fine by me, when you can sit at the swim up bar and drink all day long. the food is awesome--plain and simple. there's tons to do, and they have people who sit down with you to plan different activities (which cost more, but not much more--$120--for two people, all-day catamaran trip with food/booze/snorkling included).
plan a trip on your own, and it IS likely that you will have a good time, maybe you'll have a GREAT time, but maybe you'll be disappointed too. with a sandals trip, you are pretty much guaranteed to have a GOOD time, and most likely a great time. there's also something to be said about paying for EVERYTHING in advance, and not having to carry a wallet around at all--not even to tip.
