DH and I are vacationing in NV, AZ (first time @ Grand Canyon) and UT this year. Alas, no WDW again until '07. We are flying into LAS (McCarran Airport) because it was the most central airport with nonstop flights from EWR. I have reserved a standard SUV with National. Can we walk to our car or will I need to take a shuttle to the Emerald Aisle?
