Phillip Jose Farmer’s Riverworld.
I am gonna put another vote in for Hyperion. Also in the universe as it was after the events of Rise of Endimion once there is no more Shrike or Nemez or Tree. Yes definitely wanna skip those.
Culture.
Edenist habitat.
Matrix (Hey, it’s cool - there’s a truce, there’s only a matter of time before we get to alter it at will!)
That virtual universe (Greg Egan??) where proving mathematical theorems for someone is a form of flirtation.
In no particular order:
Niven’s Known Space
Asimov’s Foundation
Roddenberry’s Star Trek
Well my first thought was Star Wars… as a smuggler.
But Heinlein’s future calls to me.
Simmon’s universe would only be good if it is post series. The shrike is not a threat anymore and the church has fallen. The plus side? Instantanious travel anywhere in the universe.
I’d live on Moth. (The planet, not the bug.)
Count me in as a great fan of Heinlein’s Future History. But the first thing the came to my mind was Manticore in David Weber’s Honor Harrington series. Or Fleet in Elizabeth Moon’s Heris Serrano/Esmay Suiza books.
Guess I’m a pretty poor excuse for a liberal Democrat, huh?
The universe in Pratchett’s Strata.
Dumbwaiters can make anything you want, any time you want and you can live as long as you damn well please.
Plus you can have surgery to remove any pesky lousy memories you may have.
Of course, it would have to be before Jalo Jalo showed up and ruined the economy.
Culture citizens can have hour-long orgasms. There’s pretty much nothing in the world I’d rather have than that kind of plumbing 
Moving this to Cafe Society.
Oh, and another vote for Heinlein’s Multiverse.
I wouldn’t mind being a civilian in the Star Trek universe. Between the replicators and the holodeck, I’d never leave the house. And I’m fine with that.
(Wait, do civilians get replicators and holodecks? 'Cause the Starfleet unitards would not be at all flattering on my hips.)
Sounds good to me. Except that with my luck I’d be an Ensign on Security detail wearing a red shirt…
:eek:
Either Hitchhiking through the Galaxy trying to meet up with Zaphod, Ford, Marvin & the gang or on Earth C. 3000AD Futurama style 
I’m not sure; however I think everyone gets some kind of genetailoring or surgery to make them good looking…
I figure everyone has a replicator since Keiko is horrified when she finds out that O’Brien’s mother touched food with her hands.
As for a holodeck, you would probably have to go to a holo-suite somewhere. Probably got a few in every city.
The adventurer in me would like to hang out with Slippery Jim deGriz. I wonder what porcuswine would taste like.
Another vote for the Culture. I think I’d want to be on a GSV. (I love the names for ships Banks uses!)
I’d have to flip a coin between Heinlein’s universe in Time Enough for Love or Varley’s Eight Worlds. But I think it’d be a slightly uneven coin, weighted to Heinlein.
