My Ackowledgement of Spa Option paper says:
"Through the Spa Option, DVC Members and/or their guests may elect to purchase services at The Spa at Disney's Saratoga Springs Resort (the "Spa") owned and operated by Walt Disney World Co. or Walt Disney World Hospitality & Recreation Corporation ("WDWHR"), as the case may be, at a discount off regular prices. Currently, DVC Members will receive 20% discount off all Spa services, or a 30% discount off of regular rates for certain other Spa services to be specified upong opening of the Spa."
I can't wait to get a real price list of the services!
