No kidding. Gave up and went to bed a little after 12:30. Tried again this morning a little before 6:00. Got in, and was able to upload pictures, but stalled again at payment. Entered my credit card information, and the little circle just spun and spun. Tried a different browser. Spin circle, spin. Tried my computer instead of my phone. Spin circle, spin. Tried a different credit card. Spin circle, spin. Finally went back and said I’d pay cash. This time it went through and I was able to complete and pick a PAT. Got 11:15AM and boarding group 4, which seems pretty good, all things considered. Hopefully can go back and add my credit card later, or if not, will do it on the ship.
