We thoroughly enjoyed our cruise onboard the brand new Princess Regal. The ship is amazing, and we really liked the high-tech features, design, and attention to detail.
Pros:
1. The big shows in the theater were AMAZING! I've never seen anything with this level of quality before on a ship. The two productions at the end of the voyage set the bar for entertainment. There were high tech effects, multiple set changes, full 15 piece-orchestra, and fabulous singing.
The room was the cheapest on the ship... interior stateroom. I also saw that it was one of the smallest in square footage. However, it seemed fairly roomy compared to other interior staterooms on other cruise ships, based on the layout. We had a hard time sleeping without a middle sheet. Not sure why they just offer a think comforter, but it often got way too hot in the middle of the night.
