Hi there,

Then tuesdays are your best days (bisex day). You can get a colour brazalet at the entrance and state your "apetite" so other couples may know what are you looking for.

You also have on their "partner club Naked Spa" thursdays as the bisex day.

As an advice.

You can add some photos to your profile and say "hey there Gonna be there at X time" and smile once you are in the spa.

Having the first experience does not normally happen on the first day, but people is nice on the spa.
