I heard about a great deal with Costco Travel.  Right now, you can book a Disneyland package, they ask for 20% down and that you have it paid off 30 days before you travel. I found the customer service patient and helpful. 

http://costcotravel.com  there is a 1-800 number on the site and nice people answer the phones!!

My favorite tips?   Rent a locker!. You can store jackets during the day, and at night put all the stuff in there.......it's located right inside the main gate. Take some snacks and you'll save money and have some control over what the kids are eating.  Use our Travel Rx Bag  . Keep your first aid supplies, antiseptic wipes and sunscreen handy.

It is the happiest place on earth!
