A perfect opportunity to see the Indian summer (ok does British Columbia actually have one?) in Vancouver in October.
I just booked the Four Seasons Vancouver for $147.96 on onhotels.com! The deal should be available almost all October (and possibly more dates).
Usually rates for this hotel are $400+. For this day they are $413 on Expedia.com!
Reviews are glowing for this hotel on Tripadvisor (although that does not have to mean much).
The pictures look very convincing to me!
If you do not like onhotels.com you may be able to find another booking site using hotelscombined.com (this is what I used).
Also to note, the St. Regis, which isn't too drab either, can be had for just above $180/ night on that Saturday weekend!
