Or should I say person? DD, DH and I are leaving from AoA on December 1. We booked this a year ago - ADRs 6 months ago etc... Staying in LM room. *Today* my MIL decided she wants to join us for a few days. I talked to my TA a day or two ago and everything is in the mail for us. Don't get me wrong, she's welcome to join us but I have a feeling it's not that easy. What is the likelyhood of her being added to our reservations? The hotel may not be a problem... but I can't see the ADRs being adjusted that easily? Just looking for advice before I start flipping out.
