Worried about the budget for Korean makeup consultations + travel plans

Hello, my name is Pim, and I plan to go to Korea this year to get a few more procedures done. But now I'm confused about the planning 😅 It's not just the cost of the procedures themselves, but also flights, accommodation, and many other things... Has anyone been for something like this before? How many days do you usually recommend staying? I'm worried I won't have enough time to recover properly.

I've started looking for information, but I'm still unsure how much money I should save because I want to have a buffer for unexpected expenses. Also, I don't know where to find reliable exchange rate information that can actually help. Does anyone know where to start with this kind of planning?

I also want to ask, for a trip like this, should I book my procedures in advance or decide when I get there? I just found out there might be lists on various apps, but I'm not sure how trustworthy they are. Can you share your experiences? Good morning 💕
