I have seen most characters around the main sun fountain in DCA and down the street towards TOT. Cruella DeVil, Stitch, etc.
My favorite hidden thing is the moose head in The winnie the pooh ride. It is left over from when that section was country bear jamborree. You can only see it if you look up and behind you as you enter a certain "room" of the ride. I spent all of my second time through with my head thrown back looking for it...and I found it!
I really enjoy the clam chowder in a bread bowl at Riverbelle Terrace. And I just recently ate at Rancho Del Zocco. Keep in mind there are 2 seperate places to get food once inside...one has the long line, and the other which is where you can get the fantastic taco salad thing has no line! If you eat here just around dusk and get a table to the right once you walk into the dinning area, you will get to watch the train from BTMR go by! It was a lot of fun and romantic with all of the special lights they have there. Also, if you have a Disney Visa, you get a discount at this restaurant. Or at least you did the last time I was there.
I agree that Taste Pilots Grill is great! I also liked Chips, dips, and strips at DCA.
If you like Ice Cream, you can't beat Gibson Girl!
I also agree about SNA being the best airport if you can get it. Smaller and closer than LAX...and sometimes a similar price!
Candy cane inn is my fav hotel, but if you are used to the on property hotels at Disneyworld, you may want to do one of the three disney hotels. If you do Paradise Pier, get the park view! It is georgeos. If you want a good pool, and goofys kitchen, choose
Disneyland hotel, and if you want best entry to the park and having downtown disney at your fingertips, choose Grand Californian!
