I actually agree with you! I just wondered if I was understanding things correctly. Family member insists that Princess would just take our bags for us and we could go meet a separate tour. I find that hard to believe, but since they had the luggage valet thing, I second guessed it.
Yes, I do know that the gardens are in Victoria! There are several tours that meet in Canada Place, take you out to the ferry, over to Victoria to see the gardens, and then reverse. It's a long day.
