As we have always found with Princess, embarkation and disembarkation is done wonderfully. They have the process down to a science and lots of staff assisting to make sure you get where you need to go. the longest wait was for customs upon disembarkation. If you do back to back cruises from LA, be aware you must get off the ship with your passport and customs declaration; go through customs and security and then re-enter the ship. The process takes about an hour. You do not need to pack up your belonging though. We enjoyed the back to back cruises- not only for the time on the ship and seeing the ports twice, but because we had about 2 hours where the only passengers that were on the ship were those doing back to back cruises. Great time to take pictures!
We had a precruise stay at the LAX Marriott, booked with Princess, that ordinarily I'd highly recommend- but not this time. See the review of the hotel for further info.
We had a balcony cabin on the Caribe deck these two voyages- ordinarily we get one on the Aloha deck. For the few extra dollars the balcony on the Caribe deck is much bigger and well worth it in my opinion, if you enjoy being on the balcony. We had the same cabin for both voyages. Our wonderful cabin steward Renato was a very friendly and helpful fellow. He always made our cabin comfortable and it was immaculate. We appreciated his special attention to details such as regularly cleaning off our balcony furniture. On every Princess cruise we've been on their beds are awfully hard even with the egg crate on top.
Caribe deck balcony cabin: Cabin is the same size as other balcony cabins. But, the balcony is larger than on the Aloha deck. It is partially covered and partially open. Our balcony had two high back recliner chairs and two short back chairs as well as a small table. Shower is very small but manageable. There are shelves in the bathroom for toiletries and an area under the sink. There is quite a bit of space in the closet and cupboard where the safe is. We had plenty of hangers for our clothes. Bed is hard in all cabins we've stayed in. They need more comfortable matresses. Two tables on each side of the bed and a desk with a chair. There's a small bar fridge and area for glasses on top of the fridge.
