Not done on a bike tour, but this might work if you're looking for 'options'; try a cemetary/graveyard. In the late 1980s I was trying to drive home to So. California from a monutain climbing vacation in Washington (state). I was still 5 hours from home, dead tired, and couldn't find a hotel room. Finally drove by a cemetary and 'BINGO!'. I drove to a nearby housing development, parked the car, took my sleeping bag and a few other things over to the cemetary and got some real good sleep that night (my 'campground neighbors' were really, really quiet!). Got up at dawn and drove home nice and refreshed. Just an option . . .
