Hang in there Laura. The upgrades will happen. I agree that as a single, you get the "short end of the stick" to start with. It seems that the least they could do is give you an upgrade when the opportunity comes along. I'll have to talk to 'em about that!
My cousin is coming to visit from California. She has decided to cruise with me. She being claustrophobic wants a balcony cabin. We took an aft facing balcony on Vista deck. That cabin was cheaper than the 1A was for me to go single. So I plan to enjoy it. We got 9476 and I am looking forward to it.
