If you want to get back ASAP, how about getting a walk in permit? Midweek generally is no problem, and even primetime weekend permits are doable. Some great weather coming up ahead... I was skeptical, though folks here kept mentioning it, until I showed up on Friday in late July last year on a lark, and scored an overnight permit for a prime weekend. Especially if you are flexible (i.e, ready to show up two days in a row, go somewhere else for a dayhike if you lose out the first day), you should be able to get a permit before the snowstorms start to hit.
