Ok... I am going to WDW @ OKW from May 18 -May22, 2008
I am going to get the regular DDP for my 3 yr old and myself but am unsure how many days we pay for... do we pay based on days/ or nights.
We will be there 3 nights/ 4 days.
Can someone clarify this???

You pay based on the number of nights.

You receive credits based on how many nights you stay.
