I appreciate the many responses here. Unfortunately, no clear-cut answer. Here's why I posted. Our council (or district) runs a Cub-o-ree which is all-day Saturday with an overnight allowed into Sunday. I personally like two-night campouts so I inquired to the DE running the event if our pack could come Friday night. There is where she explained Cubs only camp for one-night (and then sent me that link previously posted). Because I have set in motion two-night camping for our pack for the last two years I was curious. She even admitted that packs in her own district don't follow that rule, but the rule is why her event is only one night.
Anyway, thank you all. We're going to carry on with our fun (and optional) two-night camping with smores, campfire, hiking, dutch ovens, parent cooking, glow lanterns, and all the fun stuff we do in Pack 59 (www.facebook.com/Pack59nj/).
