I will be in Las Vegas from 12-3-2014 to 12-10-2014. I usually go the second week of November and know how to bid to get both the company (Hertz) and size (Economy) I want. The last time around I bid on a Economy car and got Hertz but due to issues with the economy cars at the rental center, I was upgraded to a different size car. Long but intersting story made short: As I was leaving the car rental center, I rolled the window down to give the ticket to the attendant and the window wouldn't go back up. Took back that car and the second car they gave me the transmission was wack. The gears were sliding all over the place. Fortunatly, the attendant at the lot was able to convince management to give me an upgrade for my troubles. Back to the point: The upgrade was a Nissan Altima. We really enjoyed the size of that vehicle and would like to try and get both the company and model this time around. 1) What type of car is the Nissan Altima for Hertz? Is it intermediate, mid size, full size? It looks like Hertz doesn't have Mid Size, so I am thinking its Intermediate or Full Size. I've tried searching the web and couldn't find any information on this. Edit: I found out on another travel website, that it's considered Full Size. I could provide that site upon request. 2) What should I bid for this size? For economy, I usually start at like $10 a day, and the last few times I was able to get it for $12-$13... I figured, I'd start at $12 and try and get the bigger size for like $15 a day. How are rental cars for the first week of December? I do know that December is a slow time for Vegas, because I got a killer deal on a condo that week and the owner told me that December is a slow time for Vegas. Edit: new question... 3) Now I am wondering if I really need a Full Size, or would a Intermediate work for me. According to this other site, intermediate cars consist of Dart, Elantra, Civic, Sentra, Versa, Corolla, etc. which are all decent size cars, but that other site suggests that you could get a 2-door car, which I wouldn't prefer. Any thoughts or experience with renting this class from Vegas? What are typical bids for Intermediates for this time period? As always, when I do go to bid, I will use the links provided by the site. Thank you in advance for any advice!
