The last time I was in the CR a couple of months ago, I took a cab to Brno and back. I'm pretty confident about directions and I'm looking to rent a car when I go again next week. Just a few questions ..... 1. How many car rental companies are at the Prague airport? And can you usually rent a car on the spot or are shortages anticipated and I have to reserve in advance? Are they located across the way from the terminal? I vaguely remember seeing some rental places. 2. Gas stations - do I pay first or pump first? And do the pumps have credit card processors? 3. Regarding the highway sticker or whatever it is, I guess I could inquire about that at the rental place. 4. Do they usually allow the car to be driven across country (e.g. Brno)? Are there mileage limitations? 5. Any other things I should be wary of? Thanks in advance for your help.
