So outside the locker room areas, dry saunas and swimming pool what are you wearing? the 'spa clothes'? And, If I wanted to do this as a date night, what things could my husband and I do together?

Nothing naked you can't even wear bathing suit ( swimming suit)the only time you wear the short and shirt when you decided to go to restaurant side and each room has different kind of saunas that's available for men's and women's that's one of my favorites to meditate your self

Im going there as a date this weekend.

They provide you with a t shirt and shorts. S M L XL. They keep everything super clean. It would be a very relaxing & bonding date night. You do could get foot reflexology massages, full body massages, play "playfully" in the pool. On your own you would enjoy a french body scrub/ massage; it is discounted right now I believe, & if your brave and adventurous enough you will find that the hip bath is nice too. I hope you both enjoy!

after you shower, you can go into the common area and swim together if you choose. the shower is separate.
