When they converted the Regal Princess to Pacific Dawn they did change all the televisions over to the flat lcd televisions, added extra 3 & 4 beds to some of the original twin cabins to convert them into quads, moved the casino from where it originally was in the Dome to Dolphin Deck, converted the movie theatre to the kids clubs Turtle cover and Shark Shack. These were just to name a few of the changes that I can think of that were done during the drydock.

As for the Jewel - it'll be interesting to see what else they do as the kids club are already established and in a really good spot, they are creating a new nightclub (or hopefully two), maybe some new carpet and furnishings too .
