A spa trip is all about indulging your senses, and your therapist wants to ensure you have the best experience ever. So don't be afraid to SPEAK UP! From music to massage pressure to problem areas, don't be afraid to tell your therapist your desires so you can enjoy the best treatment. After all, it is ALL about you.

Spas can often not delay your appointment more than 10 minutes, as it will cut not only into yours but also other clients' treatment times. Make a special effort to arrive early. Not only will this give you the opportunity to enjoy your full treatment, but you may also be able to take advantage of many of the facilities many spas offer (from steam and saunas to hot tubs and fancy showers).

Make sure that if you must cancel your appointment you do so with plenty of notice. Spas are often left footing the bill for your therapist's time if you do not show up, and short-term cancellations will often charge you to make up for this loss.

Be respectful to your therapist and always groom yourself before coming in for a treatment. And if you have any problems that may be contagious (from colds to athlete's foot or rashes), please reschedule your appointment until a time that you will not put your therapist in danger of contracting your problem. Not only will your therapist be grateful, but you are also sure to enjoy your treatment more.

Avoid shaving (face or legs) the day of an appointment, as many treatments include exfoliation of the face, feet and/or lower legs, which may irritate your freshly shaved skin.

Turn off your cell phone while at the spa, not only will it distract you and your therapist but it may distract other guests. Do not wear perfume or aftershave as it will permeate the steam used in many treatments or the sauna.

Everyone knows it can be very uncomfortable having to be undressed in front of your therapist, but luckily here in the States therapists go to great lengths to preserve your modesty. If you are uncomfortable about getting completely undressed, it is usually perfectly okay to wear underwear. And for treatments that do not mix with your underwear, many spas will provide disposable undergarments for you to use.

Drink plenty of water before and after a treatment, especially saunas or steam rooms. Avoid alcohol the day of your appointment and eat little, if at all, for at least an hour before your appointment.

It is usual to leave a 15 to 20 percent tip for your therapist. Tips should be left at the reception desk in gratuity envelopes that are then passed along to your therapist. If you receive services from more than one therapist then leave a separate tip for each one. At a medical spa you tip the facialist and not the medical doctor. It is always smart to check if the gratuity is included in the price before tipping.
