I am trying to book on Enterprise's website.

So, I am trying to rent a car from LA Korean town area and return the car to the LAX.

Issue I am running into is that I would like to rent on 27th of July and return on 31st. Since 31st is Sunday, the location I am renting FROM is not open that day and even though I am returning the car to different location which will be open, the system is keep telling me that I can not rent due to return time error.

Does anyone know of work around or do I have to try to book over the phone?

Thanks.
