Just had a short chat wit a Customer support rep online.
He told me that based on my drivers licenses during pick-up the rate might be re-calculated. I the then made a remark about pre-paying the rental car, he then said if I didn’t make any changes or take any extra services, the rate would not be recalculated
I am now considering of cancelling my reservation through a big website and booking directly with Budget. It will only save me a couple of euros, but more importantly I have a coupon for a free upgrade when booking through Budget.
What are the chances of receiving that upgrade? (In my case from Full size to Premium)
