We are on Ruby to Alaska out of Vancouver July 16th so may be same cruise. We have done 8 cruises with Princess though this will be our first time on Ruby. We have been on her sister ship Emerald Princess and loved it! The full wraparound deck, Adagio Lounge, Skywalkers lounge, Movies Under the Stars and International Cafe in Piazza are some of our favorite places to hang out. The service/food is very good and their elegant decor and quiet ambience are what we prefer when cruising.
Very good decision to arrive in Vancouver the day before your cruise departs. Hope you and your family enjoy your cruise!
