Keep a printout of fare receipt!
When we were checking out of BestWestern Mainstay Inn, the staff refused to honour the lower internet room rate ($75/day) I had got when I reserved the room. When I asked them why I was being billed a higher amount ($95/day), the receptionist first attributed it to tax!
When I continued to pester her, she flatly refused to honor the amount saying that they never offer such low rates. Finally, I went back to my car, pulled out a printout of the reservation, and angrily showed it to them. Only then did the staff relent and reverse the additional charges.
This is not how the hospitality industry is supposed to work. Also, beware, the cupboards in the rooms creak when someone walks by in the corridor. This is after the large scale renovation that the hotel is currently undergoing. Altogether, this is an avoidable hotel.
