Nope..they are small and run tours every 30 minutes. The place isnt very crowded to begin with.
Is food nearby?
You might have to wait but no need for reservations.
No, we bought our tour tickets when we got there.
To my knowledge reservations aren't required, but planning ahead and saving your spot is never a bad idea.
I do not believe you need reservations. I saw people come right in and sign up for a tour.
