Oh my gosh! I went up tandem with my 10yo DS. It was the BEST thing I have ever done. We decided to do it the afternoon we were on CC. We walked right up, paid our money and got on the next boat. We had to wait about 15 minutes. My family went up to deck 9 and watched us, as we came really close to the ship. It was the most beautiful, peaceful thing I have ever done. Oh, we sailed at the beginning of May, so I guess if you are in peak season, you might want to ressie earlier.
