This will be my first trip that I've booked a rental car for more than 1 day. We're arriving June 30, and I'll be in Vegas with my wife and my brother, and mother for a couple days. We're staying at the Monte Carlo. My wife, brother, and I have all been to Vegas in the last 3 years and are all accustomed to walking. The thing is... how bad is the heat? My mom is 63 and not extremely mobile. The good thing is that it seems like it won't be a super busy week given the prices of rooms. I'm just wanting to hear from others if they've found a rental car to be more of a hinderance and hassle than its worth. For reference sake, and since cost is important to us, I'm booked at 114 total with Thrifty for the 4 days. Thanks!
