You could always do the Fantasmic Dessert Seating. You get a reserved seat for the show Fantasmic & also get a tray of goodies & drinks during the show. It runs $59.99 but sometimes fun to splurge!
Favorite restaurants:
Carnation Cafe (we especially love their breakfast!!) If you're lucky, you could even meet Oscar that has been there since almost the opening of
Disneyland. Wonderful gentlemen!!
Blue Bayou
Cafe Orleans
Celebration BBQ (if you like BBQ...this place is very, VERY good & all you can eat)
You're already doing the World of Color dining.....so that will be awesome!! We did the meal at Ariel's Grotto & found it to be one of the best meals we had on our last trip. The show is fantastic!!
The Walk in Walt's Footsteps Tour is really a good one for learning the history & trivia of Disneyland & Walt Disney. Very informative & entertaining.
Over at California Adventure, make sure you step into the Animation Building & look around.....so many things to see & it really is a nice place to take a break.
See Aladdin, the Musical at the Hyperion Theater (just down from the animation building). This musical is broadway caliber & a must for us every trip.
Hopefully that will get you started & others will add some more ideas of things to do, see & try!!!
