I'm trying to decide between August 23-28th or one of he two weeks after Labor Day in September. It is not our first trip and it will be me, DH and DS 4. The last week of August is quite a bit cheaper, but I know it will be very hot. My main question is, how busy is the end of August, I've read it slows down quite a bit. Also, is it worth waiting until September so we can go to F&W (we have never been). I've been scouting ADRs and the last week of August seems to have more availability, meaning possible low crowds? Just seeking a little outside advice!
