Has anyone had to shorten a reservation (e.g. take off 1 night) that was previously confirmed using a club UG? Does doing so trigger a rate change and/or require a recheck of upgrade availability as of the date you call in to make the change? Or is it as simple as them taking 1 night off of your existing res, and keeping the rate and UG intact for the remaining nights, without having to re-roll the dice?

Thanks..
