If I purchase tickets for 9 p.m. and 9:30 for a group of 5 are we able to stay together ?

The 9 will have to wait for the 930 to get in...I suggest the 9 group be last 930 be 1st in their group so get there around 8:45

Before entering you are asked how many people you come with. from there they place them, I saw big groups walk together

No

Not sure. Me and my friend bought the same show time

I believe you would, as long as you all go in line at the same time....they honor tickets if u are late, you just go in at whatever time slot is up...
