Nope, had 6 people , no issue
No! I was there on low season, i didn't have any waiting
We went on our family vacation. There were 12 of us and we didn't make a reservation.
You will not need a reservation for that amount. We offer group rate for groups 12 or more, however we do not require reservations for parties less than that. -Grand Caverns Manager
5 is fine but during the summer, if you call ahead then there is a discount for larger groups. Depending on the date, too large of groups might have to be split up. Always best to call and check.
You can go with as many people as you can pull along. 30 people would even be fine. No reservation necessary.
No reservations needed. They have tours of the caverns feom 10am to 4pm. Parking is free and there is a park with a pool for the kiddies.
No reservation
I would call, we went on a class field trip and had to book reservations
