If you are planning on traveling to Europe and want to know where all the sexy places to go and have some fun. I will recommend this website. It lists all the bars, saunas, restaurants, hotels, and more. They also included links those company's website and/or Facebook page.
They also have interactive maps that gives you a birds-eye view of where places are located in each city to give a better perspective of where to go and how far one needs to travel to reach one's destination.
I will have the link posted to this website in the gay travel section. I'm also working on my own Europe upcoming parties so you guys are aware of the upcoming events around the world.
