In your experience for Marriott Travel Cards, did you only allow them to be used when people were only paying Rack RAtes??? It seems the T & C's Limit the use of them, but I have used them on AAA rates and Friends and family rates in the past without any problem.. Heading to Europe next week and have a few thousand worth of them and a bit worried I will have a problem with my AAA rate booked..

Thanks
