Yes, Sesame Place had exclusive Sesame Street products that were not available at your local Toys R Us or Walmart store. I had seen that Sesame’s Forest of Fun and Sesame’s Safari of Fun Lands at Busch Gardens in Williamsburg VIrginia and Tampa Florida both carried some of the Sesame Place branded product. I’m sure Sesame Place carries more exclusive product than the two Busch parks carry. It’s been many years since I browsed Sesame Street related merchandise though, my spouse used to distribute Sesame Street plush to Busch Entertainement Corporation so I got to see a lot of the sample toys at the time but it’s been 6-7 years since then. I would think it’s safe to assume that they still carry exclusive merchandise, but hopefully the budget cuts within SeaWorld Parks & Entertainemnt hasn’t effected Sesame Place’s product selection.
Hope that helps.
P.S. as a Pennsylvania local, you all have to let us know how the Oscar the Grouch coaster turns out next year! Welcome to the forum.
