My impression is that they were required to stay together as a group for most of the day. Or at least had some sort of itinerary they had to follow--be here at this time. Now be here at this time. There is no way they got to the park at 8am and spent the entire day there until the drone show willingly. And Jenn didn't know what time lunch was...which means it was a forced lunch at a certain time.
I'm also rethinking the timeline--they got there Monday morning, that's the half day. The two days were Tuesday (which was posted yesterday) and Wednesday (which we will see today). They are flying home today.
So, even though "it's a really short trip" without the kids--it's not. They left Sunday, they'll be back Thursday night, maybe even Friday morning. So they were pretty much gone a week, After Tim was already gone a week.
I'd love to know how bedtime went for 5 nights without Tim. Did
break the habits? Did she sit on the couch, all teary-eyed, recording a sob story?
