My bike tours, I usually start well before the tourist season, and I am doing camping 90 percent of the time. Thus, I almost never need to make reservations. I almost always can show up and find a campground that has room. Or if I am looking for a motel, if it is a Mon thru Thur there aways is a room available.
But my 2024 tour, one bad day, campground on the map had gone out of business. Decided to head to a motel that was in my planned direction of travel. Got to the location, asked the gas station manager where the motel was. He said it closed, was torn down, the gas station was on the same property that used to be the motel. So, aimed for the next motel on my map. Photo below:
This ended up being a 14+ hour day, that included one border crossing, two ferries, 85+ miles of riding. Made camp after sunset.
I am sure someone here will tell me it as all my fault for not using a booking/travel agent service.
