<prompt> Human: Hey all,So I was wondering if its a good idea to open a new credit card to reap some rewards for my upcoming vacation. Looking at some credit cards, I can get things like tons of bonus rewards points by spending over 2 or 3k within the first 3 months.Id be opening the credit card, putting the vacation on it and paying it off. Is this a good idea? I have a great credit score 750 and havent opening a card in awhile.Thoughts? And what card would you suggest for max rewardscash back? Thanks!  <response>: rchurning
