I've sailed with RCCL and Celebrity a number of times. This trip was RCCL's 14 day "Ultimate Alaska" - it went from Vancouver to Alaska, and then south to Victoria, San Francisco and dropped us off in San Diego.
High Points: Really friendly and accommodating staff. Terrific weather - sunny and mild in Alaska in September. Reasonably priced excursions. Stunning food in Portofino. Free drinks for Diamond members in a dedicated lounge before dinner.
Low Points: Not the best cabin service. NOISY, NOISY cabin, just based on my location.
