The Aava is the standard hotel recommendation for bikers. If you’d rather get a condo or something similar there’s plenty to choose from. Check out AirBnB and VRBO. Whistler has a great valley trails system so don’t worry too much if you’re not smack bang in the middle of the village, it’s easy to pedal around and avoid traffic for the most part.
Bearback are a great shout. Not sure there’s too many other guiding companies available, so if you cant make it work with them, just let yourself in gently. It’s easy to get in over your head very quickly if you’re not used to the trails here. It is easy enough to navigate around the trails just with trails forks though. If you do any bike park it might be worth just getting a lesson or seeing what WB can offer as again, they’ll help show you around and find the right trails to not spanner yourself on.
I’ll most likely be around as well if all else fails!
