14 years here, never locked a dinghy, always took the "red,orange coiled thingy", never had an issue. A moorings captain told me, just be sure to bring one home.
Got a rubber band, hair scrunchy, or a piece of string?
This is a $5000 chance I will not take. It's so easy for charter guests to be so nonchalant, when it's not your property. When we had our boat, we rigged a simple rig to the D rings on the the dinghy and hoisted it with a spare halyard, instant davits. A 15" steel cable from Home Depot and a decent water proof lock can save you $$$$
