Overall: We had never before had more than one sea day. Here we had six in a row. We (ourselves and six friends) were fully occupied. We had time to do things (clubs, dancing, shows) that is tough to do if you have to get up at 6 the next morning for a 7:30 a.m. tour, so the TA gave us a chance to enjoy the ship.
Embarkation in San Juan: Took about 30 minutes at San Juan's Pan American Pier. A cab there is essential, although we arranged a van for the 8 of us and assorted luggage. Check in was fine. Most of the time is involved in walking.
Room: We had Junior Suite 1570 on the tenth deck. A very spacious room with a walk-in closet. We could never fill all of the hangers and drawers, even though we brought three suitcases of stuff. The bathroom was very nice and had a tub. The balcony was a good size, with two chairs and a table. Our steward kept the room neat and clean, with towel art about half the nights. Did I mention the walk-in closet? The room is very quiet, and no matter what was doing in Centrum, no noise passed through the door. No noise from deck 11.
Very large room, walk in closet, good sized balcony, very quiet, bathtub. We would take this room again in a minute.
