You used to be able to activate at another park than Sesame Place, but buying it this past year, it says MUST be activated at Sesame Place. We've had our Super Grover passes over several years, but not consistently. One year, we used it at Sesame Place, SW SD, and DC, SW Orlando, BG Tampa, and Aquadica. Used to also get preferred parking at the other parks than Sesame Street, but now, says only preferred at Sesame Street. I guess I will find out when in Orlando in a few weeks. I did activate my home printed Super Grover pass at Sesame Place. We live around 1/2 hour from Sesame Place. My teen and adult kid would not step into Sesame Place, but they did not have to be there. I simply showed my print out at the parking lot kiosk, and got preferred parking, used the kiosks outside the park to activate our passes. Got all our Super Grover passes, and left.
You do get free parking, and discounts on food and merchandise, as well as unlimited entry. Note because Sesame Place is not open all year, all it's passes expire December 31 of the year, unlike SW or other type of park passes, year from activating. This year, we bought in end of July, as can use our Super Grover passes, the rest of this year, and next. So, for a trip in August, worth getting it now. Usually, we buy at Black Friday, and use the following year.
