I had so many problems during that stay, that in spite of the goodwill adjustments they made on my bill for the comedy of errors, I still won't return. It was more like Red Green's Possum Lodge than the Jasper Park Lodge.

But as for the OPs question, it really does depend a lot on what they're looking to do. Banff probably offers the most things to do, both at the hotel and around the area. I personally love Lake Louise, because I just love the setting and the hiking trails that are right there, and find the hotel and finishings to generally be in better condition. Banff offers more options should you run in to a spell of bad weather. I've only ever stayed in upgraded suites at both of these, so I can't comment on the base Fairmont rooms.

I'm not sure I'd bother with Whistler unless it was for a skiing holiday in the winter. The area is still nice in the summer, but it's a bit of a hike to get there, and I think the Rockies are a better choice for summer activities and scenery.
