Why are you going with a package??? A family suite based on FL resident rate is $2.059(2 rooms, 2 tvs, 2 bathrooms, and all the kids in one room and mom and dad in the other w/ the door open of course). plus buy Seasonal passes for the 2 older children, your wife and you,$895. Thats less than $3000 plus you have tickets for a year with black out dates, 2 weeks christmas and new years, week before and after Easter and mid jun to mid Aug, But otherwise the tickets are good any other day of the year plus you can park hop at no additional fee. Plus with the suite you will get a mini fridge, microwave and coffee maker. Even if you decide to stay off site definitely get the seasonal pass, its cheaper and you can come back several times over the year. maybe even upgrade 1 of (the kid's pass) to an AP so you can get free parking. If staying offsite it will cost $10 a day to park and a kids AP is $110 more than a seasonal so for 14 days you are actually saving money by upgrading the 1 pass. An adult's AP is about $130 more. Break even and then all future parking is free for the year.
Plus you can get some discounts at some sit down restaurants at Epcot for lunch and some dinner discounts at DTD. go to
