InterContinental Hotels: Priority Club & Inter-Continental Ambassador - Honored error room rate

Did anyone experienced a situation with booking a room under price which was obviously an error (standard rate 199 $ and you booked it for 4,99 $ for example).

Was your confirmed rate honored or hotel staff fighted to charge you with the correct rate?

Thx!

If you tell me where and when, I'll let you know. ;)
