Hello: We are traveling through Columbus Tuesday night (6/17) and staying for the day Wednesday. Planning to stay at the Doubletree on Front Street Downtown and leaving the car there while we go to the Scioto mile for Tuesday evening and then COSI during the day Wednesday. 1. any potential problems with leaving our packed car at the hotel? and 2. are there any discounts anyone knows of that we could use for COSI tickets? I saw something on the website about a "pepsi panel" but I couldn't really tell what that meant.
