Questions: Travel

I'm going to be travelling around Europe, I'll only stay a day per country that I visit. I'll be spending most of my days exploring the city that I'm at, not much time at the accommodation as I only have about 24 hours per country. I just need a place to drop my bags off as I explore the city and a place to sleep when i'm done exploring, which really just put my head and fall asleep. I've heard most age demographics on hostels is 18-25 so I'm not sure if I'll be out of place as I'm 30.

I need to sleep off the alcohol a couple hours, but then I'll be off. Creepy Carl better not fuckin follow me.

Your friend calls you short notice. They're leaving at the end of the month to go on a 1-year round-the-world vacation and you're invited. They're paying for everything for both of you. You'll visit all the world's major landmarks, multiple countries, eat lots of good food, and experience lots of cultures. And of course, you're traveling in style... first class flights, luxury cruise lines, 5 star hotels.

You have to drop everything, most likely, and go. Only you are invited. Your family can't come.

Do you go?

Do you have to quit your job? Do you have enough leave time built up to be able to go?
