A cousin and I are discussing a possible three-day budget weekend in Houston to visit our other cousin and her husband. To make it easier on them, we'd like to rent a car so they won't need to pick us up at the airport or leave us one of their cars while they are at work. It has been years since I rented a car, and I have no idea what a good price is or what companies to price. Does anyone know the best priced company to work with, or any good coupon codes? (Before we rent anywhere, I do plan to check with our credit card company and make sure they offer rental car coverage/loss/damage, etc. I think I remember that is important!) Thanks for any and all advice!
