They did offer a pizza delivery service that came in from PO, I'm not sure if that is still the case, but to be honest I thought it was very over priced. I prefered a delivery from Papa John's on Apopka vineland road.
I agree.....we have a selection of menus from local restaurants in the area that will deliver to WDW resort for a small fee ($3 or less). We've had everything from pizza, club sandwiches to baked ziti delivered to OKW when we're too "lazy" to cook
The "kids" have ordered pizza several times at OKW, but that is the only thing available. You can always call for a meal at Olivias, and take the bus down to pick it up.
The pizza comes from Dixie Landings(POR) and is not the best unless you are really hungry. I would suggest you order from the services that others on this board suggest. There is no room service at OKW.
