I've been to the one in Sterling Forest. It was about 20 years ago though. It was fun. Go on a weekend when it hasn't rained the day before or the ground will be all muddy & wet. It's ALL outdoors. Wear plenty of sun block and bring a sweater. Wear appropriate shoes for uneven grassy grounds & mud. It is LOTS of walking, especially from the parking lot. I saw parents dress their kids in the stupidest, uncomfortable, dressy sandals & the kids couldn't walk after 10 minutes. Definitely ruined their day. The kids wanted to go home.
It was fun to do - once. You are really put into a whole Renaissance environment the minute you walk in. Everyone is in costume, so you can go dressed up yourself and have fun. There are mostly LOTS of booths to buy things, like Elizabethan type clothing, handmade pottery, etc. The prices were very expensive for
everything. This is on top of the admissions fee. Expect to buy a roasted turkey bone for lunch at around $7 per leg. Ribs were about the same price. Then $3-$5 for a hand squeezed lemonade. (These werre the prices 20 years ago, so it may be more.) Probably
small bottles of water are $3.
At some point of the day, there is a live chess game. The queen and her court walk through the fair now and again. You will see live improvisations with the knights and other actors doing live sword fights - if you catch them doing them and you interact with them. They are trained for live improvs. But, it is NOT continuous acting entertainment. The place is large, so you might miss all the good stuff. By the time you hear about it and rush over, it's over. You
might hear when the live chess game is, but I don't recall there being a posted itinerary of stuff, other than the joust.
There are some games. It's mostly lots of SELLING stuff, mixed in with the entertainment. It's like going to a street fair but during Renaissance times. They are out to make money.
At the end of the day, it always ends with a live joust. That was exciting to see. They use real horses and do a "real" battle. You hear the clashing of the swords and it looks like they could really hurt each other.
You don't have to go for the whole day. 3-4 hours, including the joust and you've experienced it all. There were several people who got there when they opened and didn't stay for the joust. It was too many hours of hanging out, waiting for it, and they felt they had experienced enough.
It will be a nightmare leaving. Just like a concert, everyone leaves at once after it's all over. And there's only one way out and down Rt 17K, (I think?

) So plan your time leaving and any plans afterwards to include the S-L-O-W travel out.
I had also gone to the Medieval Times dinner joust in Lyndhurst, New Jersey. I was less than enthused about that. It was all being a spectator, sitting and watching during dinner. NO interacting at all with the actors.
