Hi Lyn. I am going on the same cruise with my family. I have a 18-year old daughter, and my niece is 15. My husband and I have been on 4 other RCCL cruises. You will love it. This is our first time on a Voyager-class ship. The best thing you can do is look at the Royal Caribbean web site: www.rccl.com
. There is a great deal of information you get get from there. I would also suggest you fill out as much of your documentation on line as possible. If you don't already have passports, it's a good idea to get one. As far as clothes, there will be two-formal nights where men need to wear jackets, and women get dressed up (gowns, formal-type wear). There is also one semi-formal night. The rest of the evenings are casual. Shorts are not allowed in the dining room at dinner, but they are all right for breakfast and lunch. I have also read that if you or your children wish to ice skate, you will need a pair of long pants. You cal also get a lot of information from this web site as well.
