- I see you are going to Alaska. The 3 or 4 times I have been there I have found that Formal nights are less formal than say in the Caribbean. I'll leave it up to you to decide if the "boys" should wear suits. I know at that age you can't tell them what to do or wear.
My granddaughter just turned 15 and she loves to dress up. :-D
Have a SUPER time and let us know how you enjoyed your cruise.
