How do you save up money for a Disney World trip?

I have been going to WDW since I was 4 years old and have been going with my husband since 2006. In that time we have learned a few things. Number one- book wit the dining plan so your food is paid for up front. Next- decide how much you need for your room and souvenirs (and flight if you need to) and divide that amount by the number of months until your trip and decidhe how much per week you can put away (I get paid every 2 weeks so we put away more money on those weeks since there are 2 paychecks those weeks) Then- if you are staying at a a disney resort- this is a money managment tip- bring a minimal amount in cash and tell the front desk to tie your debit card to your room key and tell them a maximum amount (the amount you want to spend) and charge to your key. That way you can check in at the desk and keep close tabs on what you spend while still being able to relax. The saving change is a GREAT tip too!
