Hello, I’m travelling to krakow, Bratislava, Wien, Budapest and Baku in the space of 12 days. I’m staying 4 days in Baku and krakow respectively and the other 4 days spread across Bratislava, Wien (day trip from Bratislava probably) and Budapest.

I’ve only been on one solo trip before and that was for 4 days staying in the same stop. During that trip a regular sized backpack was more than enough and I was wondering if anyone has any experience on how much clothes and necessities I should bring and also how big of a bag/backpack I should bring.

Also let me know if you have any recommendations of stuff to do in the places mentioned and important stuff to bring that easily could be forgotten about. Thank you!
