My wife and I just got back yesterday. We had a great time. Thanks to a call from the cheap upsell fairy we had our one, and probably only cruise in a Cat 12 GS suite. (cabin 7306). Loved the space, but we were never disappointed with a cat 8 balcony either.
We flew in the day of the cruise and had no issues. I had read a tip to get a porter at San Juan baggage claim and they will lead you to the head of the taxi line. Best tip I ever got and the best 5 bucks I ever spent. Got our taxi- I felt guilty for about 3 minutes, ok maybe 2.
Got to the pier gave a porter at the end of the pier a tip and the bags showed up in our room 2 hours later. On board processing was quick- 5 minutes in the VIP lounge and we were on board with sail and sign card in hand. Went right to the room. We happened to get there minutes after my brother and wife who were first time cruisers and had a cat 4 across the hall.
More space than you can fill up. Big balcony. Quiet, It had a mini fridge which is not common for regular rooms on this ship.
