They do have a massage room at the BW Health Club, but IMHO she'd be missing out on the spa experience. Spend a few extra $$ and book her at the DI Spa (which can be hard to get to these days unless you have a car) or the GF Spa.
I've written a lot of info on the GF Spa including some really detailed posts on teh facilities, etc. Just do a search.
