Last year (2010) Frank and I traveled to Yosemite. We had an amazing trip. I booked most of the accommodations withing 1-2 months in advance. We stayed 1 night at the Wawona Lodge, 2 nights at Evergreen Lodge in a pre-assembled tent, 2 nights at Curry Village in a tent cabin and 1 night in Tuolumne Lodge Tent Cabin. The trip was amazing. The tent cabin in Tuolumne had a wood burning stove which we got stoked early in the night. We made the arrangement at Tuolumne while we were at Curry Village, so we got lucky with availability!!

This year we are back packing the John Muir trail. We do not have a wilderness permit, however the following links states they reserve 40% of the permits for the day before. So we're going to push our luck and cross our fingers with a little prayer! Say a pryer for us, that we get a permit.

Part of the trip we will be in Tuolumne Meadows. I am having a hard time getting accommodations for Tuolumne. I just got to campsites at Tuolumne Meadows Campground, the following is the site location.
