Planning your budget and schedule for your first treatment trip to Korea?

Hello everyone, I'm Liyun from Taiwan. I've been thinking about getting a treatment done in Korea recently, but honestly, I'm a bit nervous. It's not just the cost of the treatment itself, but also adding in flights and accommodation – it feels like the expenses suddenly add up quite a bit? I wanted to ask how everyone usually plans for overseas treatments like this.

I'm trying to estimate a budget for the treatment itself, but I'm not entirely sure about the actual costs. I'll probably need to set aside some buffer funds too. Also, generally speaking, how many days do you need to stay? Can I fly back the day after the procedure, or should I stay a few extra days to allow my body time to recover? I'm also considering whether to go alone or find a friend to share accommodation costs with.

Does anyone have similar experiences? I'd love to hear how you factor in all these costs, and if there's anything about the itinerary that you didn't initially consider but later found to be important. It feels like planning thoroughly like this will prevent me from feeling rushed and disorganized later on.
