Whether or not kitties like to travel is totally individual to each cat! I'm sure there are breeds with tendencies. Our Spooky, who isn't Spooked by much of anything anymore, would probably travel pretty well. She doesn't complain about being in the carrier, she doesn't seem to mind car rides - and she's pretty fearless about exploring new space.
But Sheldon? He eliminates everything from every orifice within 10 minutes of going anywhere in a car. He is miserable in new places. Perhaps if we'd toted him around when we'd first adopted him at 12 weeks it would be different.
I came across a rescue story where a woman rescued a kitten while on a hiking/camping trip on a bicycle. The kitty was really ill, so she had to get to town to a vet. She couldn't leave the kitten alone during the day - so she made a sling, and just took kitty along. Now her kitten is a cat - and she still goes everywhere with her. Especially on her camping trips!
Our assistant - who lives in NYC - called last week to say he saw a man walking down the street (well groomed - not homeless or anything) with an obviously cared-for cat standing on his head.
Jin said he didn't want to give the guy the satisfaction of staring - but that it was really obvious the cat went everywhere with the guy, and was really good at balancing itself on his head.
...now that's getting out and about!
