We stayed the night before at the beautiful, charming and expensive El Convento Hotel in Old San Juan.
We reached port about 12:15, waited in line about one hour before boarding. It was hot, and anti climactic, and there were many people trying to push their way in line in front.
We then went to the dining room to see our table. We have a history of not getting what we want with RCL. Yes, they had given us a table for eight when we had asked for a four. Waited a half hour, then got assigned another table. Went to see that one. It was the first table when you walk in the dining room, right by the main service station. Yuck.
Getting two balcony rooms creates lots of room. Actually I think better than a suite (we have done both)
