Does it has to be in a group ,or it can be a single or two person.

They don't have a minimum requirement for people. You can go alone or with another person if you'd like. I do know you can go up to 8 people tho.

It can be any number up to their limit. 1 or 2 no problem.

Good Morning Gladys, you are more than welcome to come alone or with a group! We max our tours out at 8 people but can definitely accommodate more than that if you give us a call.

Ya, you can go just by yourself or with a group

Single, two person works. Sign up ahead of time. They really are great! Very personable staff.
