There isn't really a "Best of" - mostly because everyones tastes are different ect. Such things are always taken with a bit of a grain of salt. But I'll try to be broad
Best Hotels
Personally I love all the hotels for various reasons, though Santa Fe is a bit hard to appreciate, due to the sparse looking design, Cheyanne is wonderful to look at - but breakfast there can be like a mad charge (plus lack of much extras, but the best of the budget hotels)
Personally I love Sequoia Lodge over the other hotels. It's just the right price, and feels the most relaxing of the hotels to me. Others like Newport for its huge pool and seafaring theme, while others enjoy the swankier New York.
Of course the one everyone aspires to go to is
Disneyland Hotel, which is certainly the best. But only if you can afford it, (seems like your going there already heh)
Best Rides
Disneyland
Pirates of the Caribbean
Big Thunder Mesa
Phantom Manor
Buzz Laser Blast
Storybook Boats (if it's open!)
Space Mountain
Autopia (try riding it at night!)
The riverboat ride (serious, theres some great views on that ride)
Walt Disney Studios
Crush's Coaster
Tower of Terror
Rock 'n' Roller
Stitch Live
Animagique
Cinemagique
Toy Story Playland (if just for the scenery, though the rides are pretty decent)
Best Restaurants
(Best Character Interaction & Best Buffet) Inventions at Disneyland Hotel
(Best "Budget" Character Meal) Cafe Mickey in the Village
(Best Budget Buffet) Parkside Diner at Hotel New York
(Best Restaurant for Food) Oooch, flip a coin between Walt's and Silverspur Steak House in Disneyland Park
(Best Variety) Agrabah Cafe in Disneyland Park (many exotic buffet items)
(Best Atmosphere/theming) Blue Lagoon at Disneyland Park
(Best Breakfast) Toss up between Inventions (for food items) and Good Morning Fantasyland Breakfast (because early park entry!)
(Best Counter Service) Matter of debate depending on your tastes, but I like Toad House the best - some lovely Fish and Chips
Mind in the case of the restaurants, with the 20th looming a LOT of restaurant changes will be taking place come April (I imagine it will, they usually use the new celebration as the time to change their menus)
