if you buy tickets now do you have to know the day you are going or can you use them anytime

You can change it. Unless of course youre standing in that line to go buy them, then of course you'd want to go at the time!

Need a date but can change

Choose a date and time, you can reschedule by calling it your choosing g date and time

You pick the date and time

You have to pick a date but you can get in line at any time during that day

I believe you have to know the day you're going
