Anyone tried to book the Spa Hair Service called Blow Out, bundle of 3? I can't figure out how one gets to pick 3 nights. After I pick one night, it charges the full amount, so when you pick the second night, it charges that full amount again! Are we supposed to just pick the first night? I hate to hold on a call with Princess as the last time I called about Spa Services, they disavowed any connection with it and said it was all done by spa company. So they couldn't even answer my question. We are going on an 18 day cruise and this is the first time that I have seen this service offered. It would save $, if I could figure out how it works. I don't know whether to trust them that once I am onboard it will get sorted out (last cruise I had some issues with pre-purchased service). It may be so new that no one knows??
