Big thumbs up on Selkirk Lodge. The terrain is outstanding and if the schedule on their website is current you'll be skiing with a top notch guide that week. I'll be going there in early March for my 8th consecutive year.
In the interest of full disclosure, saying it has "indoor plumbing" is a little bit of a stretch. Water is from snow melted on the woodstove. There's a pee-only toilet on the 2nd floor of the lodge and there are 2 propane fired outhouses. It's still quite civilized, just not what most would consider indoor plumbing.
