...consider trying a different route. Even if it's just from one trailhead over, at Henry's Fork instead of Dollar Lake, it's such a great area that it's worth an extra day or more to see more of it.
When i went, we started from China Basin, a couple of trailheads to the west, and made a 5 day loop around the Red Castle area. It was spectacular. If i were up there again, i might try coming from the south through Painter Basin. Whichever direction you come from, there is eventually a trail up to Anderson Pass.
Anyway, i'd love to make a group, but i have no way of knowing this far ahead if i'll be able to go. Good luck!
