OOOH a new Disney Planner!!!
As an adult I have been many times, and at an average adult pace for me it takes about 4 days to see it all. Anything over that is just chillax time to go back and revisit your favorite shows and attractions.
Keep this in mind though:
Big shows like Fantasmic & the fireworks will only play on weekends. Fri-Sun. Although the new World of Color show is to be premiering in June. I heard rumor this particular show many run every night for the first while.
As for getting to the hotel from the airport there are several options
a) Rent a car, but if your not going anywhere besides Disney, this will be a waste of money. You do not need a car to go to Disneyland and to stay in the area.
b) The Disneyland Express, which is like a big Gray Hound bus which will drop you off, but you need to understand that there are other people who will have to be dropped off as well, and so that can be a bunch of time wasted depending on how many drops are going to be made.
c) Super Shuttle is a company who supplies small Vans which hold up to like 8 people, and they also make drops at other hotels along the way to drop off the people in your van. You never know, you might luck out and be the first ones dropped off, but you will not make as many drops as the Disneyland Express.
d) If you fly in to SNA (John Wayne) Which is the closest air port to Disneyland, you can get a taxi for just your family for around $40. Personally to me this is the best option. Super Shuttle from SNA although LAX does have Super Shuttle as well, it is around $10 per adult each way anyways. At least for a few extra dollars you will go directly to your hotel. Personally for my family this has always been our favorite option and will use it again for our up coming trip.
As for hotels, if you want to stay On site, maybe you can find entertainment rates, or some promotional package. Usually they have some amazing deals from January to the end of April where you can stay a few nights and get 2 free. Kind of like the one that is currently going on but is holding out until the end of October where you pay for 5 nights and get 2 free. The Grand Californian is the most expensive of the on site hotels, but it has its own access into Disney's California Adventure park that only hotel guests can access.
There is however a ton of fantasic off site hotels which are closer to Disneyland then the On site hotels. The Howard Johnson is a big favorite among us Disboarders, as there is usually some sort of discounted rate going on. The rooms there are really decent, and the pool exceptional

. But I would highly recommend looking into the Carousel, and the Tropicana as well. They have great rooms and are less then a 5 minute walk quite literally to the main gates of the park. They (including the Hojo) are around many restaurants as well. Tons of option.
