I booked our spa appointments (couples massage, mani for me, shave for DH) on line when my booking window opened. Now I am reading that I may have made a mistake because the Spa runs on-board specials. If the service I booked is on special, will they adjust the price or do I pay full price? Is the price difference significant enough to risk not being able to get an appointment? Do they ever fully book? We cruise on the Fantasy next month and our date is sold out, does that make a difference? Any input is appreciated! Thanks!
