I don't know if they are "required" but I would recommend them
I was there yesterday, and reservations are required.
We didn't have a reservation in April.
Yes.
There wasn't a long wait for the reservation. We booked in the morning for our afternoon visit
Yes u need reservation ahead and ur group can be 12 people
Easy to do the reservation on line. We did for Mother's day and it was fantastic!
Yes otherwise you can wait and see if someone cancels. We got lucky and were let in because two people didn't show up. We were 15 minutes into the tour when those people showed. They were allowed in. We all enjoyed it. Due to covid they only allow half of what they used to. I think its 10 at a time.
Yes you need to schedule ahead and I would do it soon the closer it gets the harder it is to get tickets
