Our phones are antiquated, you might say. In trying to check in online for our upcoming cruise, I'm pressing the 'Web Version alternative', located underneath the download app icons, we proceed accordingly. When inserting our booking number, 'This booking has already been claimed' pops up in red and hence, cannot proceed. I've called Princess and no success with resolving the issue and told to print out our summary of the cruise and do the check in at the port. Has anyone else encountered this? I know apps are being pushed for everything nowadays but it seems rather ridiculous not to simply check in online.
