I just booked a one-night comp reservation at the Mirage for when my husband takes my Dad to Vegas in September. The offer was sent to me and the lady said that she made the reservation in my name, but that my husband can check in. We do have linked MLife accounts, but I remember once when my husband was travelling for work we met up in Vegas and they wouldn't let him check in on an offer that was sent to my email and booked in my name. They told me I had to be there to check in. I asked this woman 3 times and told her, "I am NOT travelling" with them....she said it was fine. What do you think, should I be worried?
