On 6/4/18 , arrived at National in Las Vegas and they had NO CARS!! I'm an Executive Elite status and rent with National weekly , normally a very smooth process. I'm in Vegas frequently and always use National. So I was very surprised that no cars were available. Additionally, no manager around to ask what was going on. The wait wasn't long but was annoying. Not a great way to start a vacation. National, you have to do better.
