Top 3 in Vancouver.
The top 3 hotels in Vancouver are supposed to be Hotel Vancouver, Four Seasons, and Pan Pacific.
I haven't checked out the Four Seasons hot tub personally.
I like the Hotel Vancouver's location the best out of all three and it has the nicest ground floor amenities/neighbour shops.
Although the Pan Pacific has the best view (of the water) and many (most) heads of state stay there (easy to safeguard with less approaches).
The Four Seasons is probably the best "chain". Vancouver used to have a Mandarin hotel, which was also arguably up there in the best "chain" category.
