BACKGROUND
I have cruised 14 times on Carnival, Princess, once on HAL and a two times on NCL - my least favorite cruise line, because I feel they are ruining and "dumbing down" cruising with their over use of their Freestyle(means pay more for the good stuff) concept - more fees, more costs. This was our first cruise with RCL and they really wowed us and won us over - beautiful ships, well designed for crowds, and the food and service was as good as any line we have sailed. The Serenade might be considered a little older now, but it was appreciated that they did not peddle too many extras that you have to pay for and represented a lot of what is traditionally great about cruising.
PRE-CRUISE and HOTEL
A fine cruise state room - nothing exceptional or unexceptional. See comments above about being on deck 7, above the life boats - a canopy extends out 5 or 6 feet from the bottom of your balcony, obstructing views of the ocean, socks, etc for several yards away from the side of the ship.
