Planning a 2014 trip out west that includes Yosemite. Were towing a 15' travel trailer from Florida. Our plans as of now have us leaving Zion on June 24th around noon, then staying the night somewhere. We plan to arrive in Yosemite on the 25th, sometime late moring or early afternoon and set up camp. Then we will be there the 26th, 27th and 28th, pulling out the morning of the 29th to head to the Grand Tetons. I wanted to stay at the Tuolumne Meadows campground but just read that it doesn't open until July 11th. So, instead I'm looking into staying at the Silver Lake Campground. I understand its at least a 2 hour drive to the valley from there. We plan on speding 2 full days seeing the valley and then the last day relaxing over on the east side of the park. Couple questiolns.... Anyone ever based their trip from the east side? Also, is the Tuolumne Meadows date just an estimate and could the campground open earlier? The reason I would like to stay on the east side is I wouldn't have to drag my camper over the Tioga when we leave for the Tetons. Also, its a quicker drive to the east side from Zion than going arund to the west. I'd rather run a few extra miles w/o my camper seeing things than drag it through those mountains. The morning we leave for the Tetons will be early and it would require I drive it in the dark. Any suggestions?
