It's from 3-6pm, is offered to only
4 groups at once and costs $90 ($72 with the AP).
You can order them fully loaded or omit any toppings you'd like. We've done it twice. You also eat pitchers of drinks and they refill them as much as you want. At the end, you get hats and a certificate.
On June 26, 2017 we just did it with my party of 9! It was so much fun! I highly recommend it for anyone with a big party. When we went they were more than 4 parties doing the Nacho Challenge. They had a whole room set aside for the festivities. We didn't eat lunch and we all were so full! It was one of the favorite things we did this past trip. I highly recommend it
