I only do motels/ hotels. Not much you can do at dark campgrounds. Most people go for a walk and find a fire pit chat going on.
If I have a long ride, I'll find a motel first, then have supper and then go back to the motel and likely flake out on the bed after I move the pics to the Ipad.
On shorter or layover days, I'll ride around 30 or 40 miles, depends on whether there's an attraction to see. Often I try riding up and down every street in the town. I like just seeing homes and whatever I find interesting. I might also ride down the highway and back, if the town is tiny. Then I'll look at TV and YT until I fall asleep, same on rain days.
Funny thing is, it wasn't much different on my car trips. I was just as sleepy tired. LOL.
Many days I nap at home before supper, if I'm not moving to stay awake.
