We've done a studio with a 6,4, and 1 year old. Mom and dad in the big bed, the 2 older ones in the pull out and the little one in his pack and play. It was tight but we get up early grab a granola bar and some fruit on the way to extra magic hours. We then come back after lunch, change into swimsuits and hit SAB until dinner time. We then walk around the boardwalk or go in to Epcot, and return in time to grab something at Beaches and Cream. We spend about 7 out of 24 hours in the studio per day. I didn't figure the points per hour in the room but it can't be good.
If you're one of those people that goes to Disney to hang out in the room then get a 1 bedroom. If you go to Disney to cook in a ktichen then get a one bedroom, if you go to Dinsey to do laundry then get a one bedroom.
Now, with that said, guess what we're staying in next month?? A 1 bedroom! I can't beleive it. If it's as good as everyone says, I'll let you know. We've never stayed in one before.

Laundry, TV, and eating in the room. This will be weird for me.
