I had to phone call in to make our specialty dinning reservations and our excursion for an upcoming Princess cruise. I was able to log in ok, but the app or the website would not let me complete the reservations as desired. After navigating the phone call tree, and struggling with a language barrier, I was successful and the reservations showed up on the app. Like you, I was determined to do it on-line, but now I won't hesitate to call. Sometimes I wish I was not tech savvy, and just booked the whole thing the old fashioned way like I think many must still be doing.
