We were on this cruise as well - love it!!Also Congrats! We just returned from our 1st Alaskan cruise (Aug 12-19), our 5th on Disney, and it was great! We arrived 2 days early in Vancouver BC and explored the city a little. BTW, the area near Canada Place was very walkable and we enjoyed it. We took a taxi directly from YVR to the port and the cost wasn't bad at all. And to add, "ditto", we plan on doing it again.
You will absolutely love it! Our favorite cruise ever!This will be cruise #4 for us. So excited for August 2020!! This is a bucket list trip for us. We have wanted to do this for a lonnnng time.
