Gee, thanks for all the respones. But, I guess I should have mentioned that they did not use a travel agent, but booked directly with the cruise line. (I know, just one more reason that you should use a travel agent - but just to set the record straight - I always use a travel agent and can't be held responsible for the actions of my friends
). So, anyway, they are in a guaranteed stateroom and without the booking number the cruise line told me there was no way they could help me. Any other suggestions - or should I just plan a different kind of surprise? Thanks again for all of your comments.
