looking for friends in lisbon during city safari :)

Hey i'm dave (29) a couple weeks ago me and my girlfriend broke up and we were planning on going to lisbon for the city safari. Now shes not going but i am and i'm very excited but i was wondering are there more solo travelers there that maybe wanna meet up during go safari and hang out? If we add eachother we can work on friendship for some trades :P

This is my first time outside my country in 10+ years and first time traveling solo ever :-)
