Just shy of $20,000 to go to Antarctica travelling solo (small cruise ship). More than I've spent on every other vacation I've taken combined.
Was one of the best trips of my life. It also gave me enough space and clarity to realize how toxic my ex was to me so that I could find the strength to leave not long after I got back.
I'll always want to go back to Antarctica. The inner peace I found there changed my life.
I disagree it as calling it a waste of money, because you have travelled for other destination, had a different experience, might have met international people or different people too. All such experiences does have value and you might have enjoyed to the fullest and that is a refresh yourself with more positive vibes. So when you spent money on yourself is not called waste.
