There are so many different types of Private Parties you could have, from what I understand the "Hollywood Pictures Backlot" is used alot, as well as Just paradise pier in some occasions...I'm not sure why, but i'm sure its A lot cheeper than renting out the entire park. And its usually after the park closes.
Short of buying all the days tickets you could not close Disneyland down for the day. All private parties and weddings occur after hours. If you want to close down the park early than it costs even more. When I spoke to a Wedding planner to just be married in front of the castle and really nothing else it was $55,000.
So lets that monotonehell's theory played out and you had to cover the cost of the parks tickets before they entertained your idea. This is to rent out the park, like I believe Liz did. Say there as an average attendance of 35000 guest at Disney land and the cost of a single day ticket is $83. That would be a cost of $2,905,000. Im pretty sure that you would also have to buy some of the food cost also and probably a fee for renting out the park. So no matter what its more than I'll ever have. So I have to go sit in my car and play a musical history of Disneyland, close my eyes, and pretend I rented the park out. Sniff, so sad. But a lot lot cheaper.
Sunday there was a private party at the Millionaire's building. I wanted to ask someone what it was for but I chickened out
Good morning, son
In twenty years from now
Maybe we'll both sit down and have a few beers
And I can tell you 'bout today
And how I picked you up and everything changed
It was pain
Sunny days and rain
I knew you'd feel the same things...
