My Wife and I just got back from a great trip on the Grandeur! I've read all the reviews about how old the ship is and how the service was mediocre at best so my expectations were not the highest. I can't believe how wrong these people had it!!!!!
Cabin - Our room wasn't the biggest but it was a nice, inexpensive ocean view on the 2nd deck and we thought it was perfect for the little amount of time we spent in it. Yes the TV was a bit outdated and you needed a Credit Card to open the safe, but that didn't bother us at all. We only watched TV before we went to bed and while we were getting ready, and I had no problems hiding a credit card for the safe. I'm a pretty big guy at 6'0 250 and my only complaint on the room was the shower was a little tight.
On Deck - We didn't spend much time out by the pools, but the Solarium was the place to be for relaxation. It's an adult only pool and the only time kids really go in there was to go to the grill in the back for Burgers and Pizza (this should probably be moved to a part of the windjammer) The regular pool was nice as well, and it was relaxing to have some decent music playing over the PA for some background noise.
