I didn’t mention Riverworld because (creepy voice) we are all going to visit riverworld (/creppy voice)
Why do you even need to ask? I’m off to Planet Lovetron,of course, with my dashing man about town, Darrell Dawkins…
i’m not sure about having to be naked, but the world of Phase from the first series (before the games computer got arbitrary) could be fun. Would prefer to visit as a Citizen though
Phobos, as from the text adventure game Leather Goddesses of Phobos. Just got to remember not to try and jump with that weak gravity there.
Has anyone mentioned the planet Amazonia?
Goodbye, friends. I never thought I would die like this. But I’d always really hoped.
Discworld
Gallifrey
Eriticon 6
I want to visit the Planet “Porno” from “FLESH GORDON”
Also “Mongo” (from “FLAS GORDON”
Planet Booboo.
Or maybe the one that revolves around the star Puke, but is a billion times the size of Earth. I can’t remember what it’s called.
I hate to admit it, but another vote for Risa. It’s warm, friendly, and relaxing.
It might be fun to go to Transsexual, Transylvania. Surely they have some great dance clubs where everybody does the Time Warp (again).
Uh, I think I’d like to see Arrakis (from Frank Herbert’s Dune ).
I’d like to see the Freemen with the blue eyes. And the big worms…Plus, I’ve always kind of had a thing for Paul Atreides 
Darn I wish I’d thought of that one.
Eroticon 6 :smack:
Planet Hollywood!
(Where’s my check, Arnold?)
Soror, from La Planète des Singes, might be worth a look.
I’m interested in the amusement park planet in Trek’s “Shore Leave.” You know, where Bones gets killed by a charging knight and Kirk kicks Finnegan’s ass all over the planet. Better than Risa.
No love for Gethen (Winter), eh? 
Oh, how could I have forgot that place? I wonder if it was against the rules to “conjure up” a fellow crew member?
Maui-Covenant, prior to being added to the Worldweb.
Riverworld.
Any Culture world or habitat.
As to real planets I’d like to visit, I think I’d like to visit Jupiter. It is probably the only planet in the solar system where an exposed human could survive for more than a few minutes if provided with oxygen to breathe. If you go down deep enough for the temperature to be a comfortable shirtsleeves temperature, the atmospheric pressure would be less than 8 bars…about equal to being 250 feet underwater. Skin divers can survive that.
