We tent camp for 2 weeks from July 7 to the 20 and we had a great time, it rained almost everyday, some times very hard, but we had no problem, nothing in our tents got wet, I guess is all in how you set everything, DH had a tarp on top of our tent, we had no problem with heat since we had an A/C, we were cold in the mornings, in our kitchen tent we had a fan and it was fine.
I don't know about the dinning plan, we have annual passes and didn't do dinning plan.
But tent camp is nothing scary or bad, or maybe becuase we are used to tent camp since we were kids and enjoy it.
