We are also booked on the Ruby to Alaska next summer, leaving out of Vancouver. I too have some buyer’s remorse after reading reviews-yikes! We are not new to cruising but are new to Princess. Our last cruise in March 2020 was cancelled so we haven’t cruised since 2018. I wonder if part of why people are so disgruntled is from the fallout from covid. We purchased Princess Plus which I hope is the best choice. It’s difficult figuring out the casual dining options, or other things like if there is a juice bar served at one of the bars. We don’t have massive expectations and are not too difficult to please but many of the reviews are pretty terrible . It’s good to see the reassurances from other cruisers who have sailed on the Ruby. She certainly looks beautiful!
