Our DD16 H.S. marching band will be heading to WDW in 3 weeks!!! We will be traveling on the Great Lakes line. Can anyone tell me what to expect? Other than a bathroom, do the seats has plug-ins to charge I-Pods, phones? DD16 is a Type 1 diabetic and we will need to keep her insulin cold. We have a plug-in cooler for the van, but wasn't sure if we will be able to use it. I do know that we will have a DVD player, so I will ask if we can show our park DVD's. TIA!
