I know the Grand Spa offers a lot of couple packages. I know through the month of February they offered a Chocolate and Wine Wrap. You can go to www.grandspa.com
The Spa at the Crescent is very couple-friendly. The co-ed Tranquility Room is a nice spot to wait for treatments and almost all spa services are available as couples.
The Wyndham Anatole offeres room plus spa treatments as well.
Most of these packages are pretty pricey, and depends on your budget.
They even have a service that will come to your house, and even prepare dinner in your own home. Bliss Mobile Day Spa www.blissmobiledayspa.com
Hope this helps.
