Love-tocruise, you mentioned about my girlfriend and I doing different things. You mentioned about the spa, but I and "dressing" up which we love to do. Actually we are different from everyone else, we dress up every night, but on formal night, we even dress up more.
Also, just a hint, in the cosmetics area, if one of the girls that works there is not too busy, sometimes they will do your makeup for a formal night. I knew my friend would like it too, so I ask her (she just happened to have an opening) if she would do my friend, so she did. We both felt very "pampered."
