Should I be spending $10,000 AUD (6500 USD) on my first ever solo trip? I have never done it before and I am spending 45 days in South America. 4.4k alone is flights, another 2k on accomodation, and then the rest is spending. Am I being autistic? I can't tell if this is normal, but it seems really high in cost. Do people usually spend large amounts of money on solo travel to other continents?
