In regards to you other question, you should at least spend a few days on property to see everything--I would say three days, as a minimum. It takes more than a day to see all of Disneyland Park, as it does have more attractions than the Magic Kingdom. Views of California Adventure are, of course, mixed--but I would say that a day there would probably be necessary. I see you are from New York, so it would be tough to get there and have a full day in the parks, due to the 6 hour flight to LA. Therefore, I think with three nights, you could spend the first night looking through the hotels and Downtown Disney, the first full day at Disneyland, the second day at California Adventure, and the third day wherever you wanted...probably mostly at Disneyland, but maybe split between the two parks depending on your ticket. Then, you could hop on an overnight flight back home, pay a little less due to the time of the flight, and not have to needlessly pay for another night in the hotels. Of course, you could also do this with two night--get a really early flight (like 6am), so you would arrive in Anaheim early, have three park days with only two nights in the hotel, and have the overnight flight home. All a matter of preference, but it is a bit tough to stay out too late after a day of flying, obviously (the time change makes it feel much later). But, I'm thinking with only two nights, you could perhaps afford one of the Disneyland Resort Hotels, and still see and do it all. Of course, if you have a bit more money, consider adding area attractions, considering you will be in one of the busiest places in the world. Regardless, three days in the parks would be enough to see everything in both parks at least once.
