Which of these is the most luxurious and indulgent beauty treatment?

I am getting married in two months' time and I am surprising my two sisters (bridesmaids) and mum to a day at a luxury spa a week before the wedding. The thing is though, there are two treatment days I like the sound of. Both include facials but one has a back, neck and shoulder mage, while the other has a marine detox wrap. Which should I go for? Also, with the wrap, are we likely to be all spotty by the wedding day as it is supposed to remove impurities and toxins? Help me out here!
