From the official Facebook event page:

"Join us on Labor Day weekend, September 1st, 2nd & 3rd (11am-6pm daily), to witness an invasion of Norsemen ready to educate you on the culture and history of these explorers and warriors. See details as they are announced on our facebook page or www.sleepyhollowrenfaire.com.

We are also excited to announce a major change in pricing for this year, while technically the pricing will stay exactly the same as last year we are moving to a weekend pass model. Meaning, when you buy your ticket it is good for the ENTIRE weekend you purchased it for. So if you attend Labor Day weekend your $19 dollar wristband will get you through the gate for all three days, or for both days if you attend the second or third weekend. Season Passes passes are also available. Tickets will go on sale mid-spring at sleepyhollowtickets.com.

Ages 5-12 Weekend Pass: $8 Adult Weekend Pass: $19 Adult 3 Weekend (full season) Pass: $48 Parking: $5 per vehicle."
