So annoying. so I was booking 2 room online and entered all my credit card info and the very last step was to enter my TR number. so I did and as soon as I pressed enter rooms rate went up $20 each night for the room. Called and was told there's nothing they can do... argh argh argh... So being a total rewards member you get charged more? should have just skipped it... sigh... Sorry end of rant.
