I am divorced for many years and have full custody of my two children. While discussing European vacation, passports and so forth a travel agent told me that in some instances it is wise to have a letter from non-custodial parent when traveling with your children. We are booked for a March, 2004, cruise. Has anyone ever been questioned about this sort of thing on a Disney cruise? My two children have a different last name (I have remarried) and I did not know if we might encounter some problem. If push comes to shove, I could probably get such a letter, but would much rather not even go there with my ex. (Children don't see him often, and I would just as soon he not even know about the trip.) Anyone traveling with children with a different last name who can tell me of their experience? Thanks!!!
