Last cruise on MG I booked steakhouse reservations for a couple who were our travel companions (linked) and they booked Tempannyani reservations for four. We both had OBC. Somehow I was double charged for one set of the reservations. My OBC was charged as was my credit card. I tried to get my 75 dollars back and was unsuccessful even getting an Executive Resolution Host involved. It was some kind of glitch but I was not happy they never credited me back. Be careful
