Disney owned spas are not open yet but Mandara Spa over at the Dolphin is open! I went there for the first time yesterday for a massage and it was fantastic. Prices are much better than Senses as well, only downside is no AP discount but they do offer a DVC discount. I still prefer Senses on the whole but I wouldn’t hesitate to go back to Mandara. I believe Swolphin hotel guests get a credit for the spa on certain packages as well, at least that’s how Marriotts tend to work elsewhere.
