We flew to Los Angeles the day before the cruise and stayed at the Marriott. It was a great place to stay. They picked us up at the airport and carried us back the next day to catch our shuttle. The hotel food was extremely expensive so we walked across the street and ate at a Mac Donald's. We chose the Princess shuttle because we were not familiar with LA and felt unsafe to travel not knowing our way around. The shuttle worked out great and embarkment was a bit long. It took about 45 minutes to check in, then you had to go to another holding area and wait to be called. All in all it took over an hour and a half to get on the ship.
The lido deck staff kept tables cleaned and helped seat you. I really do like how on a Princess cruise the silverware is on the table for you and they bring you your drinks even in the Lido deck. It was also kept clean and ready to use.
Our room was an obstructed oceanview. It was just standard size, plenty of closet space and a very small circular shower. It was adequate.
