First time we are going with our cell phones. DH and I both have iphones. As you probably know, the batteries do not last long. We don't plan on taking away from our experience when we are in the parks but beside taking pictures and looking at the MDE app and possibly using it to keep the kids happy in line I'm wondering if anyone has any tips or experience on keeping their phones charged or from going completely dead. Are there ports anywhere now that you can sit at when you are taking a break? Can't you buy like external chargers and has anyone used one? Weird question probably, I know. Thanks
