Just made an one-way booking on Alamo.com using Costco discount codes. Per it's T&Cs:
Drop Charge - This is a fee that is assessed for renting a vehicle in one rental location and returning the vehicle to another rental location (see one-way rentals). This is also known as an 'inter-city' fee. The drop charge fee varies by rental location and time of year. The drop charge fee will be disclosed when you book via the web site and is payable at time of pick up.
Since the only fees disclosed during my booking is the taxes, does that mean that this particular location does not assess any one-way fee? Thanks.
