All of the above (we love it) but also -
So compact. Easy to go up to ToTWL, down to pool, a short 5-10 to Contemporary shops and food.
For us, the decor is more our style but also its a calm escape from the parks and everywhere else. I love that its simple and quiet and I think it helps our kids calm down too. I love the Disney crazy but in our room its always pretty chill. Especially with a lake view...it's such a break, its lovely!
For midafternoon nap breaks from MK, it simply cannot be beat. We spent happy days in MK from 9-1 and then 4-7 with happy rested kids. Loading up the stroller in the morning (waters in the bottom basket, kid toys and cups, etc) and not having to completely unpack them at any point..not for a bus or anything! The pack and play fits in the laundry room - a bonus for midday naps, nice and dark!
