Good Morning My next cruise isn't until August. I just paid the final payment, and wanted to bid on a higher class cabin (I have a balcony now). I logged into the website where you are supposed to bid, but when I do, a message tells me something about "within 30 days" Do I have to wait within the 30 days of my cruise in order to be able to bid? I am new at this...any tips? Thank you!
