Explorer of the Seas, Seattle to Sidney reviews please

I was just on a cruise with Explorer of the Seas, Seattle to San Francisco and was so impressed I'm looking to take a longer cruise next year. The Seattle to Sidney cruise in October, 2018 looks inviting yet I haven't seen any reviews for this longer trip. Can anyone provide pros and cons of this longer voyage?

You can get a feel of it by reading roll calls.
