I'm planning a trip to either Big Bend National Park or Big Bemd Ranch State Park for mid-December with my two boys, ages 10 and 4 in my 80. I'll only have two days there. I would appreciate any tips y'all might have on where to stay and specific trails to drive that are scenic and moderately challenging. Since we will be going by ourselves, I want to make sure the choice of trails isn't likely to lead us to be stranded, but at the same time I'd like to give the 80 a bit of a workout and the kids an adventure. In terms of lodging, we will need to stay outside the parks because their rooms are already booked. Don't want to camp. Any thoughts on a decent motel that won't break the bNk but is clean and convenient to the parks? Thanks in advance for any advice you may have!
