The WP pass idea could work well. Can you stay a month at the YMCA in Tabernash? I used to stay there or at a B&B in Fraser (sorry, I've forgotten the name - and it has changed hands, in any case). Is the Worst Western still open? It was a pit, and priced accordingly. Maybe you could find a trailer to rent in Granby. If you have capital, you could simply buy a studio in Snowblaze and sell it the following year. Maybe you can find a Snowblaze owner who will give you a reasonable price to rent for a month instead of a weekend. Snowblaze is right on all the bus routes, so you don't have to worry about the bus schedules. One goes by every few minutes. Snowblaze has (or had) a perfectly good hot tub, where you can listen to the tourons tell you about their amazing extreme skiing experiences on Cranmer. And you know that WP skiing has to be better next year than it is this year!
The WW must have been before my time. The Best Western is now one of the nicer (and more expensive) places in town. I've known peeps who got really good deals on dive condo sublets in Fraser but not for less than three months... not to say one month is out of the question. Yes, Snowblaze still has a couple of hot tubs. The outside one is pretty nice.
