We received 2 free 25 minute massages as part of our 4 night package promo for our booking for this December which we have been told by the spa has a credit value of $43 each and could be applied/upgraded towards a more expensive treatment.
We have also learned that if do the membership tour we get a coupon/voucher for a $150/200 or so massage credit.
I had anticipated combining these two benefits towards the cost of a sensual or erotic massage, but the spa emailed me and said they cannot be combined towards a single purchase.
