I just answered my own question by doing a google search and found the Citipark website. All is good and parking at Canada Place is only $12 Can.
Much less than the $22.80 offered by the hotel, which would require taxi cab transit to the pier etal. This is much better.
I'm also pleased that the Zaandam and the Saphire Princess both use Pier 30 in Seattle which will make the transfer from one ship to the other quite simple. All is good!
