When you sign up for your massage, they almost always ask if you prefer male or female. If they forget, just tell them you would prefer two female spa employees to do your massage. Most of the spa employees are women anyway.
We have also always had ladies at Couples and every place we have been now that I think about it.
I recommend you go for the longest hot stone massage available! You will feel like a wet noodle when they are finished with you. I think the SPA is one of the things I look forward to the most when we are heading out to Couples. Wish I could afford to get one a day!
