How much money would I need for a Disney/Universal Studios vacation?

My boyfriend and I are planning a Disney/Universal Studios trip in February. We are going for 6 nights and 6 days. We are going to stay off grounds in order to save money. We are planning to get 4-day passes to both Disney and Universal for the both of us. How much money do you think the entire trip will cost us? This is our first big vacation alone and I am oblivious to all of the costs. Thanks!|||Two 4 day passes with no water park or park hopper options will cost you $468 plus 6.5 % tax. You don't mention transportation. Air fare? From the Orlando airport to a Disney resort is free. Hotels outside of Disney property are not necessarily less expensive. Some have sporadic shuttle service, others do not. Six nights could be anywhere from $300 to $2000. If you have your own car and will stay off property, you will have the Disney parking $14 a day. Food up to you Disney has many food plans connected with resort rentals. Off property - for two - probably close to $150. a day Do you want sit down restaurants or fast food and snacks? Sorry with the information I have I can not tell you much more. However and only as a estimated guess, I think you could manage 6/6 days for $2000
