They suggest that you make reservations, but will take your group if they have room.
I've been there several times and have not waited longer than 20 minutes
The tour was included with our fieldtrip. I would suggest calling ahead of time to guarantee a seat.
We showed up and they reserved a spot for us on a tour later that day. I would suggest calling ahead to check.
Didn't need one
Just give them a call if you're gonna drive from over 1 hr away and make sure they still have space on what ever time tour you want to take
Nope. Just show up
We didn't need one.
No reservation un my case.
