"I checked the prices for parking lots P1,2, & 3 and it seems to be double the price of P6, P7. Is this information correct? "
Holy mackerel, I just checked the prices and they have gone up considerably since our July trip. Im pretty sure that we were paying 12.95/day in P1,2,3. $20.00/day is getting pretty steep. We used to compare it to getting a car service to the airport ($75.00) and is was cheaper to drive and park the car. I think I'll be checking out Avistar! I've heard good things about them.
