Let's Rent a Car and feel like being a local for even on day or tw, three days...
If you plan to stay within Tumon area, you may not need of renting a car, because there are trolley bus goes around every 10 minutes.
But if you are one of adventurers and can drive a car, you should try renting one. One of good place to rent it is from Rent-a-car company at Guam International Airport.
