This is a certain NO. I just received in the mail a couple of days ago the list of places of redemption to spend your rewards dollars. I was suprised to find out you can't even spend them at all places in WDW like I thought you could. I was under the impression that no matter where you were on property of the parks that you could use them, but not so.
Example:
MK-Guided Tours
Shopping:Emporium, Pirates Bazaar, Fantasy Faire, Briar Patch
Dining:Crystal Palace, Cosmic Rays, Casey's Corner, Liberty Tree Tavern
Room charges: I think at all Resorts it can be used
Although in DTD you can use it for: Fulton's Crab house, Portobello Yacht Club
Some of the finer places to eat that aren't on your
DDP is covered as well:
Artist Point-?, Victoria's & Alberts, Flying Fish Cafe, Jiko's, <not finer but not on DDP--> Beaches and Cream Soda Shop, California Grill (might be on plan?), Kona's, Hoop-Dee-Doo Musical Revue <--not fine> Artist Palette-?, Olivia's Cafe'-?, Spoodles-?, The Hollywood Brown Derby, Chef's De France, Le Cellier, Rose and Crown, all I think are on the plan but wanted to list them just so you got an idea of what's on the rewards list for some of the nicer places.
By the way, anything at the POP resort it can be used to buy things there shopping/or dining, room charges. Looks like you can use for all value resorts dining halls and shops. Some dining in Dlx not all but most, and some shops if not all in Dlx as well as Mod resorts.
Can also use for WDW passholder membership
If there is anything specific that you want to know, just PM or post the ? and I will answer your ?.
?=not sure if it's a fine resturant but not on the DDP
