Yes, don't do it, it is not intelligent to do a month long one way rental, since one way charges are DAILY! Get a car for a day or two one way, if possible, then return it when you get where you are going to, again, if possible, so as to stop the one way charges, and get a local rental to drive around for the rest of the month, which you will return to the same location, so as not to incur the punitive one way charges. Understand or do you have questions?
