With tickets now more than double and tripple the cost they were downtown, I doubt you'll have trouble getting in.

Do they announce who is guest starring in advance or is it always a surprise?

It says that they will announce the REGULARS shortly and that those people are scheduled to be guest stars but it doesn't say who will be guest starring when. Surely all of them aren't guest starring every show. No need to be rude.
