Thank you for all your responses. I'm not too over-worried about the length of delay - it's to be expected these days I guess. My major concern is if the delay then goes beyong the 'opening hours' of the car rental company - in this case - Budget. We have already signed up for fast track and I'm wondering if we arrive in Sanford, say, at 11 or 12 pm (midnight), can we still collect the car from the fast track depot or do we have to wait at the airport until they open in the morning?
