Have you ever been to DL before? I can't recall...sorry.
Well, in any case, I haven't been to the ToT party before, but I'm going this year and really excited by all the pics and things I've seen. So I'd say to go. Have you been to
MNSSHP? It's not that big so you might be disappointed if you try to compare the two, kwim? But the park is really done up nicely and lots of different characters out to take pics with.
Carnation Cafe is really good, get the Baked Potato soup. And ask if Oscar the chef is around. He's been working at DL for over 50 years and I've heard he has great stories of the early days. It would be neat to have a pic with him.
At the Blue Bayou, I'm sure you know to ask to have a water side table if possible.
Are you planning a tour? They have the Walk in Walt's Footsteps tour which also includes lunch so that's nice. And you'd get some behind the scenes info as well as a peek into the lobby of Club 33.
The chicken alfredo lasagna at Wine Country Trattoria is really good. Everyone I've talked to who's had it, loves it.
Gotta try a Tigger Tail. They are sold down by the Winnie the Pooh ride.
I personally enjoy the "
Disneyland: The First 50 Magical Years" show with Steve Martin. It's an exhibit about the history of Disneyland.
Gotta ride the Haunted Mansion since the Nightmare Before Christmas holiday layover will be up. That's really fun.
It's a long shot, but if you are really sweet lol and ask one of the CMs working at the train (the one that goes around the park) if you can ride in the Lily Belle, they might let you. (Find a male CM and show him a little leg!

)

Just recently another DISer I know asked and her and her DH were allowed to ride.
I'm trying to think of things that are unique to Disneyland.
Oh, the Billy Hill and the Hillbillies show is really funny.
Mr. Toads Wild Ride, since that's gone from WDW now.
The Tiki Room still has the original show.
The canoes that circle Tom Sawyers island are kind of fun. I've heard they don't have those in WDW.
Ride the carousel in Fantasyland and look for Jingles. It's supposed to be Mary Poppins horse. I think it had bells around it's neck or something. A pic on that would be cute.
The Matterhorn of course. And Indiana Jones ride.
Storybook Land canal boats are really cute. The line is usually long, BUT the little scenes are so adorable and make great pics.
I guess I have to say Finding Nemo, lol. It's pretty much a must do as well. Although I am claustophobic so I hated it.

Still, I did it at least once.
Also the Mark Twain is a must do, and I've heard you can ask the CMs working at the dock if you can ride up in the wheel house.
Ummm, well, that's all I can think of off the top of my head. LOL Just go on everything and have fun!
Also here is a thread (it's short) that you can glance through real quick about some of the favorite snacks/foods at Disneyland:
