>>Did Dana have a cell phone?<<
I was looking at it carefully, and believe it was a camera (which surprised me, as I've always wondered why we never see them taking pictures). I think she just disengaged... and I also think she looked disappointed when Phil said, "You're still in it!" Yes, she's a shrew, but that wasn't the first time he had asked her for directions and then didn't listen to the answer.
I know that Sheri and Cole haven't done any traveling, but one of the things you learn when traveling is, if you think you're lost, don't keep going!!! Stop, pull over, review the directions/map, ask somebody. Don't keep driving and hoping somehow the right path will reveal itself. Plus, when Sheri was complaining that there wasn't anything around, she was driving past some buildings about a block off the road -- yes, they're not on your path, but come on, see if you can find someone there!!!
As one of the women was climbing the stairs to the slides in the gold bikini, a local woman was walking down, fully covered, head-to-toe (although her face was visible) in the type of outfit worn by Muslim female athletes in the Olympics. (I just Googled it... it may have been a burqini.... yes, apparently that's a thing...)
