Lyn, my wife did not ask for a conversion. We were find letting the CC be charged in Canadian. The person giving the quote has a screen in front of them with the rates and a conversion box for the US or whereever. The person told my wife BTW that will be "X" in US dollars. My wife asked her if she was sure and the person repeated the quote.
My wife tried another place. When she was givng the Candian amount the person did not convert it, so my wife asked. It was the same amount.
What happen was this. the places my wife called were using the same type of sofware for the booking, I guess they are under the same umbrella of service. The software was converting it wrong. That would not have mattered because it is up to the CC and others to do the conversion. It just get off an alarm when the amount she was quoted was so high.
