I haven’t even thought about packing yet haha, probably the week before we’ll put a suitcase together. I am also attempting to pack carry on only for a two week trip- we’ll see how it goes. We leave Toronto the Tuesday before and have 3 days in Rome before the cruise.
I just booked as well, two days ago, and was getting the same error. About an hour ago I got the upgrade email, so it likely will just take a few days.
