There are three half hour sets with a 30-45 minute break (I forgot exact time) between each set. About 20-25 minutes before each set, dining package guests are let in on one side of the theater and they get the first few rows on that side of the theater. Then about 10-15 minutes before each set, the standby guests who are queuing on the other side of the theater are let in to fill in all of the available space. Depending on the act, the theater fills quickly. After the first set, the entire theater empties. If you want to see the second set standby, you immediately go and queue in the standby line again. Same process for third show. If you want to see all three sets, this is your process unless you have a dining package in which you will be able to use that line for one of the three sets. The die hard fans will start queueing at least one hour prior to the first set. The most you will stand in line for the second and third set will be 30-45 minutes (again I forget the exact time). If you want good seats for the second or third set without a dining package and without seeing the first set, you start queuing right before the first set ends before the crowd rushes out and gets back in line. Same with the third set. Whether you can get a good seat by getting in the standby line after each set really depends on the act and popularity, but in most of the posts I’ve seen, people were able to get into the theater at the last minute for most acts.
