Reward Credit Cards for a Frugal Time

You have no idea how excited I am. I’m going to be taking a Caribbean cruise but that’s not the exciting part. We’re staying in a suite. My wife and I are going to wake up in the morning and step out on to our private balcony to see the ocean. We aren’t amongst the wealthiest people in the world and I’m quite the penny pincher so how are we affording a suite made for the wealthy and why am I agreeing to pay for it? Our rewards credit card is making it all possible.
