YES! Difficulty with elevators, unless they're glass elevators. It's gotten worse the past 2 years for some reason. I almost lost control on the Atlantis submarine last year, even though it has windows.....that one was more KNOWING we're way down under the water and therefore still confined. Was doing lots of deep breating, with my eyes closed so I could try to pretend I was elsewhere. The people around me kept asking if I was OK.I just said I had a really bad headache to avoid freaking out Tyler.
Holly, DH has severe claustrophobia. Long story, but I will tell you that he slept on the deck during the Alaska cruise. You should really look into something to help if you think this is going to be a problem. (this is one of the reasons we are still looking for an upgrade)
