pay in full?

Howdy all...
I'm going to piggy back my question on here since it relates...
When I'm booking a package thru Disney, what are the time frames? Deposit is due right away and then how long till remainder? We had to push our trip back until May 2012 and I'd love to just book now and start paying a little each month till we go (like a layaway Disney trip! lol).

$200.00 deposit and full payment due 45 days before arrival.
