I want to travel somewhere in Europe with a big gay scene, great architecture and nightlife. I would be looking to fly in June, July, or August. I see that prices online are about $1200 even on lower cost carriers from Philly to Barcelona near July 4th or even NYC to Barcelona. Any cheap places I can go from Philly or NYC? I am flexible on destination and timing. I like the idea of London or Berlin or Amsterdam or Barcelona. My home base is Philly suburbs.
