Hello,first time in the USA , and all of the accomondation i found while searching the internet was quiet expensive..we re two girls from berlin/germany and we re looking forward for the festival,we dont care for anything reg.the hotel except that it should be close to the venue and payable...if you re still searching for ppl to share a room also let me know,as long as we would have our own key this would also be perfect!ps: we re only attending wed/thu/friday, maybe saturday as well but no ticket for sat.so far thank you for any advice!!! isa
