We just booked a Persian Garden pass for our 14-day TA this year on Reflection. The price is $ 319.00. To my surprise they've added 18% gratuity, being $ 57.42 per person. This seems very strange to me. I buy entrance to the spa, not a service. The only contact I have with the staff is when they give me the key to open it, which should be included in the entrance fee anyway in my opinion. Also I feel a gratuity should be optional, not mandatory. Besides, I also can't remember having paid gratuity when buying the pass on board. Does anyone have experience with this?.
