But seriously you don't have to be overwhelmed, there's tons of intermediate terrain at whistler if that suits, and plenty of helpful staff as well as free guided tours of the hill if you want to get shown around.
There are also two really good guidebooks written by locals and available through amazon I think
My first time out west was at whistler for a weekend and I knew after the first morning that I'd be back many times.
I am curious to go to Jackson sometime, and BC interior too
Im not sure I would go to Whistler to ride intermediate terrain, I want some agressive riding. Im pretty sure I can easily figure it out in a day or two, I understand the mountain is huge but I dont see that being an issue for our group of friends. Thank you for your input.
