We also went to Sandals in Antigua. It was nice, but I guess Paula is right, it may be overrated. The resort itself is nice, the Rondovals are a rip off, we did not stay there but some of the people we met did and they are not worth the money, and it's noisy around them. The restaurant food was good, and we like the buffet breakfast and lunch thing, the food is different everyday. We loved the fact that everything is included and we could go scuba diving. I would say the only thing we really didn't like was we got bored. But we are the type to be on the go all the time. Then again it was really relaxing. The town is really crappy and there's not much to buy.
But I think you have to decide what you want out of the trip, relaxation or on the go type stuff.
