Disneyland is generally quite expensive. You may be surprised at the cost of things, such as souvenirs, but food is alright. There are places where you can get good food for good prices, like the Plaza Gardens Restaurant, an all-you-can-eat-buffet, on Main Street USA. But you'll have loads of options if you go to Disney Village. And also there is the Plantation Restaurant, Captain's Library Restaurant, Marco's Pizza Parlour and Smuggler's Tavern & Traders Cafe Bar in your hotel.
Your best bet for times in Disney are at night, early in the morning, or at eating times. At night, most kids are gone, leaving the lines alot emptier. At eating times, alot of people go back to their hotels or have reservations in restaurants and in the morning, not too many people have gone in yet, so you have a fairly good chance of empty lines.
The best rides in the Park are Big Thunder Mountain, Space Mountain, Indiana Jones, Pirates of the Caribbean, Autopia, Mad Hatters Tea Cups and It's a Small World.
And in the Studios, Rock 'n' Roller Coaster, Twilight Zone Tower of Terror, Crush's Coaster and the Studios Tram Tour: Behind The Magic.
