I must admit if they tell you to go to row 2 and you want back row just tell them you want row back row and they will let you. Groupers keep the station from overpacking so people aren't scattered around with people skipping or don't know which row to go. Saves time believe me.
Deja Vu was bad until they had a grouper, so instead of taking a extra 30 minutes to get on the ride when you get in the station is only takes the next train or two.
Viper without a grouper is a chaotic nightmare! I remember CAD in July; the wait in the station is just as long as the wait in line!
There's no definite lines, people getting into different lines, lines not moving at all for some reason. You seriously want to leave the line and not think about the crazy mess.
Waiting for Demon I've encountered two times when people don't know there's two separate lines at the air gates (hopefully you won't what I'm talking about). I get in line for the second row... this woman tells us we're cutting in front of her (we weren't, she was in the other line). So we just ignore her and go to the front row line.. Guess what? The igorant woman tells us we're cutting her again! (She had sort of an attitude also) We explain to her that there are two separate lines. So we're nice and offer her the place for the front row and we'll go back to the second row (she had a large group).. but she just let us wait in the front row line in front of her.
People are ignorant! Like there would be a line that wide!
