Best place to park points
Hello, I am just starting to earn points to take my family on a trip to Europe in 2019. I signed up for SPG and am about to hit the spend on that. I just signed up for Chase ultimate rewards. These cards have an annual fee that is waived in the first year but of course next year I would have to start paying the fee. Is there a best place to transfer and park your points so that you do not have to pay fees to keep the cards open until you are able to use the points?
