If you are desperate then I think you safest bet is to buy a new drone, test it ,well away from trees, before you go on holiday then throw yourself on DJI 's mercy and see if they would come to some arrangement regarding a refund, partial or complete on the returned wrecked drone and a switch of the care refresh to the new drone.
I see no reason why they should partial return etc. but who knows you may catch someone on a god day.
THere is something called the express service with care refresh but I think you pay an additional premium on top of the excess for that service and I think, knowing Sod's Law, you could guarantee that with such a tight deadline things would go wrong and it would not arrive before your departure.
Plus, taking that to be true, with you being away it might even get sent back to DJI whilst you are away.
Oops I see Sod's Law is popular today.
BE WARY of second hand drone bought in a rush, you will need to verify they are unbound. If you go to CEX or a face to face with an ebay seller, before you hand over cash test whether or not YOUR controller AND YOUR APP can 'work' the drone with out any binding warnings arising,
To see if there are any binding warnings I suspect that all you will need to do is pair your controller and app with the drone but I would also ask if you could start the motors with the CSC BUT NOT take off, so DO NOT give it any throttle. If they allow you to do that then to shut the motors down just hold the throttle closed or execute another CSC.
