I camped Olsen some years back, and got there early, but even up against the trees you get wicked morning sun. We were able to tuck behind a fallen tree to get partial shade, but the tent was still hot shortly after sunrise. Bring shade. A canopy with a tarp or sheet for a wall, and the tent under/behind it can help a lot. You can also get affordable freestanding hammocks to sleep in the open air in the morning when skeeters are sleeping. I got a battery-powered fan and set it on a chair next to my hammock and put a bandana over my head and earplugs in and slept pretty well on some hot mornings.
