Emotional question: Plans to go on a training trip to high altitude

Hello! I've been thinking about getting a Korean massage recently, but one big observation has me worried — how much will it cost in total? The price, the lines, the services, the turnaround point... I don't really understand how to plan for all of this. I've been studying for a few weeks now, but I'm wondering about the emotional burden of getting a massage abroad.

Approximately how many days do I need to stay? Is the procedure itself done during this time, or do I have to wait for the conditions between the days? I think I need to plan carefully to include flights, hotels, meals... all of this. Some people are bombarding me with complaints about it being expensive and stressful, but that doesn't seem to be the case.

Has anyone been wise enough to go this route? How did you plan? Any tips for planning a smooth turnaround point, or any special tips? I'd love to hear from any of you!
