That's a sticky situation. A few thoughts:

a. We don't think you can check out via the app and not actually leave with the vehicle. It's not really "checked out" until you physically leave the lot and an actual gate/lot attendant marks it as such. Our take is that this is a non-viable approach as your reservation will eventually be canceled.

b. From what we know of Avis' program, you should be able to get the points back if you cancel a points reservation prior to the pickup date. The agent may have misinformed you (or it's possible we are misinformed). Someone else in this forum may know for certain, but we'd advise calling Avis again to check. Ask for a manager if necessary. You might also email and send them a message via Twitter for good measure.

c. With regard to the rate, you may want to request a quote via AutoSlash. We can typically find discounted rates other sites cannot. Feel free to PM us if you need assistance.

Hope this helps. Safe travels!
