I was hoping to get some advice from my fellow flyertalk members.

I made a reservation online in New York City for 2 days. Plans have changed and I will probably be arriving about 3 hours later to pick-up my car. I tried rebooking my reservation but the rates have double. Is it possible to keep my reservation but come in 3 hours later to pick my car up. My return time won't change.

If anybody can shed some light on this question I would appreciate it.

Thank you
