Surgery slot during high season

[hiameenion]

Hi fellow PF users,
So I'm supposed to do my surgery by the end of this month if not because of corona virus.
Due to my work, I can only move the date to this Christmas holiday between Dec 20 - Jan 3 or even worse, May 2021.
I really really wanna get my revision DES done as soon as possible, so as soon as the border restriction in both my country and Korea are lifted, I'm planning to book my ticket to Korea.
The thing is, December is the high season for plastic surgery and most reputable clinics seem to require 10% deposit to secure a slot.
Do you guys think I can still get a surgery slot even if I come without prior appointment as I have 3 clinics that I shortlisted right now, and since my surgery is a revision, I really really wanna get f2f consultation before making up my mind on which clinic I should do my surgery at.
If anyone has experience on surgery during high season, I would appreciate it!
Thankyou
