We were on the Crown Princess in Feb of this year with 3 other couples. My S-I-L paid for me and my brother (celebrated his BD on board) to take the tour. It was almost 4 hours long and the places we visited and what we saw was very, very, interesting. We ened up on the bridge with the Capt (upset because we were running late and he wanted his pm tea) and then to the Champage Bar for drinks and goodies. I came away with a chef's white jacket and a beautiful ship's bathrobe (that I gave to S-I-L as she paid). I'd have to say that it was a workout and even climbed several sets of ladder type stairs to take us within the apparatus that is hiding behind the louvered bars high up on the top deck. I have no idea what she paid for us.
