I researched for this rental and completed my trip this week. I thought I should share my experience before my memories fade out.
I found Budget Car Rental was convenient for several reasons - price, 24-hour open counter inside the terminal without any shuttle.
What I didn't like - long queue at the counter. I landed at around 11:30 pm. It took about an hour to get my luggage. Then I went to Budget Car Rental counter and asked for my booked car. The long queue took more than 45 minutes. We arrived at the hotel at around 2:00 am.
GPS direction to return location was not right. Do not trust GPS near the airport. Follow the directions only. Directions are pretty good. They change it like the way we change our chair and table. So be careful. I missed a direction and had to drive 10 more kilometers with so much of stress in the very early morning. My flight was at 7:55 am. It was very uncomfortable when I missed the direction to car rental returns.
Final car return time was not bad at all. It was very quick.
