Regarding whether to go to the lounge or lunch first....we prefer lunch. Since concierge is the first on the ship, there is no crowd at Cabanas, which we prefer for lunch. We have no problems finding a table outside in the shade and no lines at the buffet. It gets more crowded as time goes by but we can start out with the place to ourselves basically. Then when we are done, we go to the lounge, do the meet and greet, and can usually get into our room immediately after that.

why do you prefer cabanas for lunch?
