What was the rate? Was it at the outside range of possibilities, e.g., $105 a night for hotel that might have other rooms at $389, or was it something clearly in error, e.g., $1.34 a night instead of $134?

I'm happy to push the $105 a night but don't think you can reasonably expect to get the $1.34 a night.

On the other hand, .... I suppose I do watch the airline mistake fares and might someday take advantage of it with the expectation that I will fly. The difference in expectations is that I have completed the purchase when I buy the airline ticket whereas I have only made a reservation at the Marriott.

Perhaps the other part of the expectation is that I don't expect to ever discuss airline pricing mistakes with an airline employee since I'll use electronic check-in.
