I am going to be taking a group of kids to Orlando in July for a convention, and on their days off they want to visit WDW. We will be staying at Rosen centre on I drive and are trying to figure out the easiest way to get there. We will have bus passes but I am having a hard time finding route info. Also I am going to be the only adult with 13 teens on two of the days so need to stay together, any ideas? Thanks
