The main reason we do not wish to use the auto train is that it's double the driving time to and from the station. We are not huge driving fans. We like to travel, but we don't really love driving. We want a rental because while we will have to drive it obviously, it still seems easier to us than always needing to find a ride and then wait for a ride, especially with 2 kids, and we will be doing a bit of moving around while in the Orlando area. But at no point while in Orlando will we ever have to drive 5 hours, and that's about how long it would take us to get from our home to the auto-train. And that's a little more than double the time it takes us to get to Philly. So Philly it is.
