Is there an RTD (Regional Transportation District) bus line that travels from ILG to Harleysville PA?
I'm from Denver coming in for my son's Graduation.
Go to google maps click on directions, put in Wilmington De and Harleysville Pa and times, click on bus icon, it will show you public transit information, looks like a train and a couple of buses to get there.. Does not look like there is any public transportation from the airport, at least I could not find any.
There is an airport van
but it looks it is an expensive service.
This is definitely not a trip you want to do via public transit. Rent a car. ILG has pretty much zero in terms of public transportation links, and even if it did, getting to a place as small and as far away as Harleysville is going to take you most of a day, I'd guess. It would be a drive of a bit more than an hour in no traffic--which will almost never be the case, especially now that I-495 is closed in Delaware.
An airport shuttle is the only option if not renting a car. As of midnight Septa trains are not running because of a strike so even if there was a local bus to Harleysville, which I have never heard of you couldn't get to it. Normally you could take the train to Lansdale and a taxi to Harleysville but at the moment it isn't possible.
