We stay in the family suites, and while they are about $30/night more than 2 regular rooms in the values, you get a QS bed in the bedroom (vs. a double) and the kitchenette with the fridge & microwave. There are also 2 tvs, 2 bathrooms, 2 closets, 2 wall safes.
It is cheaper to stay in the family suite than it is to stay at WL cabins or in any of the villas.
Like a previous poster mentioned, if you have 1 kid under 3 (an 'infant' in Disney standards) then you can do Port Orleans Riverside... however it will be a tight fit in the room with 6 people. Plus you only have 1 bathroom, 2 double beds, a trundle & a pack n play.
Feel free to ask me any additional questions! DH & I thought about 2 seperate rooms in the values for our March 2010 trip (we have additional friends going, and could make 1 room a 'boys' room), but he said he didn't think we could go without the kitchenette! We ate breakfast in our room each day, minus the day we went to 'Ohanas for the Lilo & Stitch breakfast (yummy, btw).
