Will it be crowded? (six flags great adventure)?

well, it depends. If you go in the morning, about half the population will be going to church. Also, some may be questioning like you and decide not to go, which may reduce the population. Also, if it's 86 some may think it's too hot and not want to go. If you have a season pass, I say it's worth it because it's not like you're paying!I relly hope you have fun!(:

Generally if it's crappy weather on Sunday then the park is pretty dead, but if weather is good then it does get crowded even on a Sunday. 86 degrees seems painfully hot for walking around Great Adventure...unless you go to the waterpark, but still it seems pretty hot (in my opinion). It's a better option then going on the next Sunday since it'll be Mother's Day and people will be using their "bring a friend free" coupons then.

The crowds wouldn't scare me as much as the hot sun...wouldn't want to walk around or stand in line in that weather.
