I just canceled mine before seeing this card. Usually I get a small drop which goes back up in the next few months. I don't churn a lot of cards but Disney is one I've opened, downgraded, closed fairly often. I'll apply probably late April/early May to time the card benefits to last through a few of my trips without paying an additional annual fee 'if' I decide it's not a keeper. It takes 2 years (with Chase) for a card to drop off for 5/24 purposes. Right now, over a year's period, I think this could be a keeper. My 4 grands cost me quite a bit.
How long have you had the Premier? At least a year hopefully.
