When you arrive you check in at the spa reception. They will ask you both to fill out forms, normally contact details, details of any health conditions or medication. It is very straight foward.
You will be given slippers, towel and robe and brought to the dressing room where there will be lockers for you to put your clothes.
Normally you arrive am hour before your appointmemt time so you have time to use the pool etc and have a shower afterwards.
For a facial and massage after my shower I put on a pair of knickers (they may give you disposable one).
You then normally go to a relaxation/waiting room and your therapist will come to the room and call you. They will bring you to the treatment room.
They may or may not have a foot spa where they do a foot soak/massage
The therapist will ask you to lie on the couch under a blanket/sheet without your robe, sleepers and to lower the straps of your bra if you are wearing one. They will leave the room for a few mins for you to do this.
Given you are getting a massage most likely you will be asked to lie face down. The thearpist will return and carry out the treatment.
You maybe asked to roll over on your back during your treatment. Your therapist will lift the blanket while looking away and you will roll over /or stand up off the couch and change position if that is easier.
The therapist will the cover you again and finish your treatment. Remember only the area they are working on will be uncovered at one time. If your leg is being massaged your back and other leg will be covered.
After your treatment you will most likely be given a list of the products used and brought back to the relaxation room. You may be offer herbal tea/water/fruit platter etc.
