Not a crazy question at all - we've been booking the same way for months. So far we've done DC, Nashville, NYC, and San Francisco. We have San Diego in a couple weeks, then a single night with single day car rental to Buffalo to go see Niagara. Later we have Denver, Seattle, and Portland... We're paying out the ... for a Yellowstone/Glacier rental, but otherwise it'll be an urban summer. When car rental rates are $100+ a day, I'll happily take an Uber into a city and walk off all the food and drink.
