I spoke to a Princess rep yesterday (got right through by some miracle). She said it works best to sign in with your Booking number not your password. Go to princess.com, click on Booked Guests (not log-in). Under "Get Ready for your Cruise," click on Manage Booking. There you have the option to sign in with your Booking number. You have to already have a booked cruise, however. She also told me they've known about this problem for months now.....
