Having read numerous reviews in preparation for our first cruise, I will add mine in hopes of helping others. We are in our mid-fifties and travelled with our young adult daughter and her boyfriend.
We stayed at LaQuinta Airport East (Miami) pre-cruise and would recommend it for its good shuttles from MIA and to POM.
Embarkation went smooth as could be at POM. We arrived around 10:30. Rooms were ready by 1:00.
