There's heaps I haven't done in Disneyland and a couple of things I haven't done in DCA.
The first would be... Splash Mountain ... in any park... and I plan never to do so... Then theres that little story book train thing in Fantasyland, and the Alice in Wonderland ride through ( although, I wanted to do this last time I was there and it was down for refurbishment), and Tom Sawyers Island ( or is it Pirate something ?) - which will also be a 'not going to get to do that ' thing I think because aren't they altering that area for the Star Wars land?
I haven't been on any boats in Rivers of America - I just find them slow and a bit boring.
I also haven't been into Goofy's bounce house because I'm too tall
... and a grown up
Close your ears Keith - but I haven't been anywhere near the Princess meet n' greet thing either ( Fantasy Fair?).
I've only eaten at one sit down restaurant - Blue Bayou
Does it count if you've ridden the same thing in other parks but haven't bothered in DL because once was enough? ( things in that category would by the Main Street Vehicles, The Paddle steamer, the jelly fish drop)
In DCA, I haven't ridden anything that whirls you around - I would hurl on that orange stinger thing ( or whatever its called now) and the Silly Symphony Swings... and have not and will not be going anywhere near Disney Jr shows... I also haven't ridden much in A Bugs Land - only the Flik's Flyers... although I will do the rest one day. I also haven't ridden (and will try to avoid at all costs ) Grizzley River... I hate getting wet - splashed is ok, but drenched is where I draw the line. Another one I probably won't ever bother with is Goofy's Fly School ( my joints will thanks me ). I also haven't ridden ( and won't get to) Luigi's Flying Tires. And finally I haven't ridden the Red Trolley Car , but definitely will next time I'm there.
