We had a mini suite on Emerald deck before and loved it, due to late booking we ended up the a balcony on the Rivera deck which was very nice. The mattress needed to be upgraded and the AC at the lowest is at 72, so we always bring a fan.
The big show numbers and the comedian in the Princess theater was boring. The costumes designs were the worst we have seen and the "Elvis" Las Vegas routine was almost comical in being so bad. I would suggest the movies on TV.
Tendering to Cayman and the Princess Cays can be tedious. We were in line for over an hour coming back from the Cayman excursion to get back on the ship. The Princess Cays have a loud band playing outside the compound that competes with the band that Princess provides, which we loved. We had rented the blue shell beach chairs, but finally gave up, the noise.
The local staff on the Cays are surly and just there for the paycheck. Fortunately, the ship food staff comes to the beach and does a great job.
We had the early self walk off departure, so we showed up in the right place and no one made any announcements, the doors opened and chaos ensued as everyone tried to leave at once. Before there was someone in the lounge giving directions, so I assume someone just slept in and missed the early shift.
