First off, welcome! :wave: Now, personally I would reccomend, going on the 6th because more people will be spending the whole day there on the 7th for HHN. There probably won't be a drastic difference anyway, but I think your best bet is to avoid HHN days. Either way, you should be able to easily do all of IoA's major rides, which are all incredible. I hope you have a great trip!
