Perhaps I am a bit obsessive, but I usually call about 45 days in advance and then again one week in advance. If you just waited until 7 days before and there was a problem it might be much tougher to fix. At least if there is a problem at 45 days out you still have a chance of fixing the problem. I reconfirm EVERYTHING.... meal PSs, rental car, hotel, air travel...HTH.....P
