I can use what Marriott Reward Points I have and pay $217.88 for a mini van for 9 days with unlimited miles. (Book through Marriott Rewards website) Does that seem like a good deal? I've only rented from Alamo before and am a bit worried about using Dollar or Thrifty. I do understand that there is a fee for an additional driver. I didn't drive last time so I don't think that is a big deal. Thoughts?
