Well I guess now that ya'll have all terrified me of what
could happen

I'll just ask my TA to book us a late night flight, or a super early morning flight at the worst case. I'd rather not have any mishaps on my first cruise. I have enough circuiling around in my head about what to remember and what to do that I dont' need any added stress. And this is 6 months prior! (what can I say, I'm a planner!)
Seriously, thanks for all of the advice though. This board has been so helpful.
