Sled skiing at Vail Pass is super easy. First, get a map - it shows the hybrid use areas, which keep sleds and cats on the established routes.

Most of the skiing is off Ptarmigan/on that side. There are five main areas:
Machine Gun Ridge
Queen Bee
Boss Basin
Cupcakes
Tele/Wilder Gulch
There's lots, lots more, but those five should keep you very busy; our first season, we pretty much stayed at mgr.
You'll find that the repeat offender groups have their own names for stuff. We call Ptarmigan pass "the fences," as an example.
Queen Bee is really good for mellow powder skiing, and a super short commute. Same with boss basin, but boss is benchy - too far skiers right, snowboarders get marooned. Not bad on skis.
Cupcakes - we call the whole north facing aspect of ptarm "cupcakes," - is arguably the best skiing. Long run, fun terrain, but the commute is often HORRIBLE. Long and gets bumpy.

Be nice to the catop. They make it REALLY easy for us to ski. This goes for Buff Pass, too. The Vail Powder Guides are really cool people, we're all out doing the same thing. We get along great with them.
If you abandon a sled at a drop, move it way out of the way. Same at picks. In queen bee/boss, the cat makes a loop at the pick. Dump your sled in the middle of the loop, not the middle of the road.
I leave my key in the sled just in case they need to move it. They know how, they're respectful.
As a rule, VPG skis single fall line stuff with minimal obstacles and traversing. We try to not ruin the "postcard snow" for them. Heck, the skiing between their runs is often better.
If they're loading or unloading, we stop and get out of phase with them.
If you're coming up behind the cat, hang back, they'll move over and let you by. Getting out of phase with them is good for this reason - we're WAY faster than them.
If you start with Queen Bee and Boss Basin, figure out where the top and bottom are, go from there - you'll get a lot of good quality skiing (once it snows again). Follow the sun, a lot of the time. Be careful in "cupcakes," aka Avalanche Bowl, it is named for a reason.
Skiing @ VP is really pretty good; PM me if you know when you'll be there, I can point things out for you.
