Yeah its taught figure out what works the best. The FACEBOOK post Ive made mostly point to SFNE, but also Canobie, LC, Great Escape, Etc.
To get a big enough event besides having the attendees the park may require food, they might not. That I will ask to them about. I know the food is a tougher sell for SFNE because of dining passes. Other parks its probably an easier sell to the people because if its included in the price then people don't have to worry about it, but it also has to be priced correctly to be able to attract people! If we do this, I want to make sure that its priced right, and the event is what people want.
I know people are all about ERT, TOURS and some fun, usually a Q & A session Depending upon the park, then food comes into play.
