As long as your trip is not in a sleeper room, you can have your points returned to your account for free.

Since you are taking a short trip I am going to guess you are not using a sleeper, so you shouldn't have a problem. Simply call AGR and ask them to redeposit your points.

And Silly me, I forgot to Welcome you to FlyerTalk. Well I see you have been a member for a year and half so you're not new. So welcome to your first post!
