only suggestion - consider buying CDW if you use rental car

search my post about what happened to us on our early Sept last year Yellowstone trip. We had hailstorm damages on our rental car.

Long story short, Mastercard paid $2282 repair damage, we paid $312 Loss of Revenues and Admin Fee after lots of stressful moments.

CDW costed $16 a day for our 5 days rental that we did not buy - did not think about the weather possibilities. Last year even late August there were several heavy snowfalls in YS.
