As others have mentioned, you can book a package with a $200 deposit. You CAN make payments. Once you have your reservation number, go onto the Disney website and enter your information. You'll need the ressie number and the phone number you gave them whne you booked. Then your ressie will pop up. On the bottom it says "make a payment." You can make your WHOLE final payment (which is due 45 days before your trip) OR you can make any payment in at least $20 increments.
