I'm a frequent renter of motorized transportation when in Vegas. It doesn't work for everyone, but it works well for me. I have used Costco almost exclusively the past five years, and had always found they offered me the best rate. Alamo is my agency of choice. Prices weren't so great via Costco this spring, but they weren't out of line with the rest of the rental world. I'm running into the same experience for September. The less than $25/day rate I'm use to paying for a full-size car is no longer the norm, it appears. So I'm looking at other options. About right now I wish I had booked a "Hotwire" choice for a full-size car for under $150 for my five-day stay. I also happen to have a Sam's Club membership, and they offer some better deals than Costco is offering. (I can't get a car via Costco for less than $250, and this is for a five-night trip, Sunday thru Friday.) Their better deals are all via Sixt, which people seem to be happy with, even if you have to take a second shuttle to get there. They sound very customer friendly. So, have we seen a permanent shift in the market for Vegas rental cars, or has Costco simply stopped cutting deals on rental cars? I got so use to using Costco that I rarely shopped any other service, and I always found Costco's rates for Alamo to be cheaper than Alamo directly. I have no loyalty, per se, but I've had good experiences with Alamo, and like it much better than Budget, so I'd pay a few bucks more for an Alamo car, but it may be time to give my business to Sixt. I'm guessing they don't let me choose my vehicle, a la Alamo, and I can live with that. Anything I need to watch out for if I use Sixt? Thanks, and blessings to all.
