I'm assuming from your name you are 23? All of the dance clubs at PI are okay, but you might find them half-empty in October unless it is a Saturday night... We usually go in September and you can swing a dead cat in most of the places. Also, now that they allow under 21 year olds to wander through PI, there's lots of roving bands of 14 year olds walking around on a Saturday night. The only time we go out at Disney is to the House of Blues on Sunday night at 11pm...It's service industry night, and the place is rocking with great DJ's spinning house music. It draws a huge crowd.
Do you have a rental car?
Give the groove at CityWalk a chance on weekends. It's usually packed. But my advice is to just go downtown! Start at the corner of N. Orange and Church Street and walk north. There's a nightclub on every corner, and that's where all the action is and where all the locals and tourists in the know go. Also, before midnight, ladies get in free most places, at a lot of them DRINK free til midnight, and drink prices are normal, rather than grossly inflated by Disney standards.
There's something going on every night of the week downtown. Google Orlando Nightclubs, and you'll be sure to find something you like. Here's a list of our faves:
Antigua (MUST-DO on Friday nights for hip-hop with DJ Magic Mike. get there early!!!)
Blue Room (later night)
Cairo
Dragon Room
Icon
Sky 60 (my personal favorite, up on a rooftop)
Saphire
Slingapours on Wall Street (a great place to people watch)
The Roxy
Tabu (been hit or miss lately, see if they have a big name DJ when you're there)
Ybors Martini Bar
Zinc Bar
These are mostly upscale, dress nice to get in kind of places...there is also your typical assortment of college beer bars downtown too.
I hope I've helped a little...I am not a big fan of JellyRolls. I can go to Pat O'Briens or Silky O'Sullivans at home. When I'm on vacation, I want to go out somewhere different!
