Hi Amandaaa, My wife and I arrive the same day but luckily a little earlier. We were there last year so my information is a year old.. lol It is unlikely you will get a dinner reservation but there is a couple of a la cart restaurants that you don't need reservations for. My favourite was the Mexican one located across from the buffet restaurant. You should check it out.
Jan 15-25 -20C without windchill this morning. -30C with and both of us work outside all day! Thursday morning can't come soon enough!!!!!
