I know plenty of people who could never possibly endure the idea of being shorted even a singular dollar, so it's hard to advise anyone in this regard. To me it's like the vending machine that occasionally takes your money, and occasionally gives you two for the price of one. Now if on closer inspection this sort of thing were to happen often (in the hotel's favor) at a given property, I'd take great pleasure in furnishing Corporate with evidence to the fact.
