I'm not sure what your wife is looking for, but I've been to the Grand Floridian Spa for massages several times, as well as for facials and a spa manicure. Service is excellent and the facilities there are wonderful.
For Mothers Day in 2002 DH and DS got me a spa treatment at Disney Institute and then for my birthday in September 2002 they got me a spa treatment at Grand Floridian. While they were both incredible, I did like the GF just a bit better.
If you call them they can fax you their menu of services with the prices and a full description
