I am looking to rent a car for the convention. I am less concerned with the price than with convenience. For those that are familiar with the airport in Vegas, can you tell me which is the easiest company to rent a car from...in other words, I dont want to have to travel or shuttle off site to rent the car. Does anyone know which car rental companies have their counters AT the airport? Also, I am a convertible person....is June too hot for a convertible in Vegas?

Thanks,
Judy
