First of all, let me show you where we are right now: sitting at the breakfast bar in a hotel in an Arkansas town called "Lonoke" that may very well have been the setting for The Shining. (The hotel is actually very nice in the morning, but last night, when we were wandering the hallways looking for our room: totally kept an eye out for Redrum.)
We didn't mean to be here, exactly (although it's a very pretty part of the world) - what happened was that we stopped just outside of Memphis for dinner (more on that later because oh my godddd), with the plan to just wing it and find a place to sleep on the outskirts of town...and then our kids both fell asleep. Instantly. And what I have learned from this trip so far is that if the kids need to nap, let 'em nap; if everyone feels like getting out of the car and running around in a parking lot, go ahead and do that, even if it makes you arrive somewhere an hour later than you'd hoped. Just go with it. The destinations are less important than the journey, you know?
And so we decided to get a head-start on the next day's drive while the kids were sleeping and find a place to stay somewhere in between Memphis and Arkansas National Park, and then discovered that these "places to stay"? They're like an hour away from each other around here. And all of them, inexplicably, are completely booked up (presumably by people like us who were all "oh I'll just find somewhere to sleep tonight"...and then realized that there would be nowhere else to sleep for two hundred miles so they better get a room like now).
