The Ultimate tickets cannot be upgraded - because they're offered at a heavy discount compared to 3/5/7 day MYW and Premium tickets, they won't do it on ultimates. You could get a 7 or 10 day MYW or Premium ticket and upgrade from there.
Normally put on your Disney room key. You can add 'charging' too (you choose which cards can charge ). If you're on Dining Plan thats added as well. One card does it all!!

I'm not sure that I understand why this would be the reason. When upgrading tickets Disney only deduct the amount paid off the price of an Annual Pass.
I sent an email to Disney last week asking if we could upgrade them and am currently waiting for guest services to get back to me as they are checking, the guy that got back to me didn't seem sure either way.
