You can certainly bring your Mtn. Dews or any other non-alcoholic beverage of the sort. When you get your documents, it will include luggage tags. Take one of the tags and tape it to the outside of the 12 or 24 pack boxed drinks and it will come to your room with the rest of your luggage. You could also just pack them in a suitcase if you don't like the above suggestion, but that's what worked for us.
