Sounds like a good deal given that tickets to the event are at least $45.
Here’s more from the Burbank press release:
When patrons book a room at a Burbank hotel via www.visitburbank.com for a staycation on the night of October 18, they simply send their confirmation number and the name of the hotel to info@visitburbank.com. Complimentary tickets are valued at $55 each, for a total of $110, and will be available at the check-in booth when they arrive at the Biergarten.
