To me, the words "private transfer" in and of themselves set the overkill bells in motion. While I almost never recommend Badaling, in your case, it might be worth consideration because you could pop up there by yourself (train or taxi), do things at your own pace, and go somewhere else (e.g. Wudaokou) afterwards.
