Some questions about a trip to Disneyland?

Ok so me and my girl scout troup want to plan a trip to Disneyland with our troops money, but we don't know if we can afford it.

We are 13 years old and there are 6 of us, plus 2 adults.

We will probably take 2 cars, get 2 hotel room, and stay for 2 or 3 days. We live about 365 miles from Disneyland.

How much do you think the following will cost?

-Gas

-Tickets

-Hotel

Also, what are good hotels near Disneyland that aren't to expensive?Some questions about a trip to Disneyland?
it will cost each of you between $200 and $300 each not including food,

stay at the Annabella hotel, very clean, great pool and you can walk in to the park through downtown Disney, it's about $100 or $25 each a night but worth it.

tickets are around $150 but look for deals, you may find them for $99

gas should be no more than $20 each

good luck
