Went to check in last night and I couldn't even get past the guest information screen. All four of us were set as something other than US citizens and I couldn't bypass the screens without uploading a picture of documents that just don't exist. Correcting the citizenship information can't be done ourselves and necessitated a phone call, unfortunately. This particular sailing was booked through Costco during the early booking window. I normally book everything myself on their site but had to call it in for this reason. It's just so annoying that despite having had the information repeated back correctly and having sailed DCL before the family would have been incorrectly designated. I can't even think where in any email confirmation or ability to view my reservation I would have ever caught the problem and been able to correct it ahead of time. We were able to fix it this morning, because of course the call center is closed in the middle of night, and completed check in and are okay with our PAT. All's fine in the end, but it was more than frustrating to have something go wrong, especially for something that should have never been an issue.
