An example ...
On my 3-month cycling tour of Australia in 2004, my cycling partner and I wanted to spend a day doing an organised bus tour Fraser Island. We asked the caravan park manager if we could store our stuff securely for the day, and he said we could lock it all in a shed. So we left the tent up, but loaded everything else into our panniers and locked our bicycles and everything in the shed.
Then we caught the shuttle bus to the dock where the tour would begin. The shuttle bus picked up passengers in various locations, including right outside the caravan park.
And we spent a very enjoyable and worry-free day on Fraser Island.
We did something similar when we spent a day on a cruise out the the Great Barrier Reef, as well.
