What are you looking for?
Five star? No star?
English speaking landlord (biker friendly, natch)
Gated compound with armed dogs?
Full on bikermate rave with likeminds or polite silence?
Seriously, put the start and end points of your journey into Google maps. Slide your finger along the line to about halfway. Look at the towns and villages around that point. Pick one, two or more and ask Booking.com to throw up some suggestions for the single night of your stay. Pick the one that suits you best. Do it once and you’ll know how to do it the next time. It’s fun, it’s free and they can’t touch you for it.
PS As you are passing through the bikermates’ paradise of the Ardennes, you’ll find something somewhere to suit you. I promise.
