P-Con: Pombagira Experiences to Share?

[qos]

Last year, my first at Pantheacon, I'd heard a lot about Pombagira. I even bought some red clothing to wear -- and then found out about the "locked door" policy and the late starting time, and realized my outfit was probably entirely wrong for the vibe of the evening.

I still am intrigued by it, but here's my issue: I tend to be an early to bed person, and I also tend to be easily overwhelmed by large groups of strangers and by loud music. I'm afraid that if I attended, I would get pushed into the exact wrong headspace and then have to endure to the end of the event or argue hard to be let out early.

Can anyone who has attended Pomba in the past give me a bit more info about what the experience is like, and whether or not it's actually okay for someone who ends up not enjoying it to leave early?

Thanks. . .

ETA: Just did a bit of googling. . . I really didn't know who/what Pomba Gira was before. . . Methinks I am simply going to have to gear up (mentally, spiritually, and garb-wise) and push my comfort zone a bit. . .
