Philly actually I think recently has been a better option than Charlotte, and if it allows you to get home on your regularly scheduled flight with no stress of missing the connection OR even worse, missing the connection and possibly having to spend the night, that is what I would do. I loathe a very stressful flight home. That just ruins all your vacation calm!

With regard to what to check on Global Entry, that question had come up here before and I can't remember what the resolution was. I thought someone said there was a Netherlands Antilles and that's what you're supposed to check. If not, I personally would probably have put the Netherlands, as the Dutch side is where the airport is.
