Wind Surf or Star/Spirit

Thinking about a cruise on one of these in the Caribbean. Is the bigger Wind Surf better or the smaller Wind Star/Spirit better? Any opinions appreciated.

We were recently on the Windsurf and were somewhat disappointed as it was tired and in need of an overhaul. Also, we expected a bit of a younger crowd but the average age was probably in the early seventies. Perhaps this is because it has an elevator. We will try Windstar again (service was excellent) but it will be on one of the smaller vessels.

We have been on the WindSpirit and next month on the WindStar. We like the ship alot. I have friends who were on the WindSurf and thought it was too many people for the facilities. I don't think we would like the bigger ship and probably won't try it.
