sightseeing&Sziget? (Budapest)

Hey everyone!
Its my first time trip to Budapest and i am traveling alone.I just arrived the city.
I wonder is there anyone who wants to attend to Sziget and also wants to discover the Budapest. I am not a type of a person who likes to be alone . So if i can find some friends who has same plan with me it would be nice. :) Please write me if you want to join!! Have a nice day all!!
Best Regards
