Fastest is to walk, the more enjoyable route is via train in my opinion. Please note that they have really reduced the appeal of Toontown in recent years, all that's really left is Roger Rabbit's Cartoon Spin, Meet Minnie and Mickey and Gadget's Go Coaster. Most adults can't go in Dinald's Hous and Goffy's Hous is now boring compared to when it was a bounce house and they have eliminated Chip and Dales Treehouse. Sorry, just my opinion. The area is well themed, but so much of it has been remodeled to eliminate the fun or has been closed. Ok, sorry that came off extremely pessimistic, wasn't my intention. Even in it's heyday it needed work though.
