...use some discretion This is Mexico, so use some discretion. The Stic is like many other Mexican "Baños" where, although much action can take place, one must take some care and use the "golden rule" of allowing the other to make the first move!
I have not been to these baths for some time, but there is steam, Turkish and cabins where most of the action seems to take place. Try to get a cabin above no. 20 as you are then far away from the attendants!
