so you are getting a 2-bedroom - once you see the size of the livingroom - dinning - kitchen - not to mention the hallway going to these spaces - no more answers will be necessary.
you will have room to spread out.
beds
master - king bed
livingroom - queen sleeper sofa
2nd bedroom - 2 queens
it can sleep 8.
there are 2 baths - one a combination (2nd bedroom), the other - next to the master has both a whirlpool tub and a shower stall.
the kitchen is fully equiped.
you just have to bring - detergent and fabric softener for the washing machine and dryer. they are in the laundry room. (it is the only DVC resort to have a laundry room - the others only have a closet)
also bring - aluimium foil, ziplock (or whatever baggies you use).
I bring candles and bubble bath (only use a tiny drop or two) - but since your girls are bringing their boyfriend - that might not be a good idea.
OKW can be very romantic.
the slide is probably too young for them. It is shaped like a sand castle - but it is fast.
disney stuff - well it depends on where you will be - some of the villa have Mickey mouse heads in their balcony fencing - also other places around the resort in the fencing.
there is Mickey or Minnie in some places along the sidewalk.
some people use to think the main pool was Mickey's shaped - but it is not.
half basketball court (this was added later - when there was a demand), couple of tennis court, volleyball, 4 pools, 5 bus stops (so you don't have a long walk from anywhere to a bus). the commuity hall has some more games - computer ones plus board games (for raining days) that you can check out,
viedos and DVD.
you can rent bikes and boats. although I would rent a boat at the Polyn first.
It is a community so to some people it does not feel like a resort. Some of us love that, others hated it.
would get groceries at
www.wegoshop.com
or
www.gardengrocer.com
unless you will have a car. some people think a car is necessary at OKW - but it isn't ready. the big problem with OKW bus system is just getting out of OKW - with 5 bus stops it will take a bus a while to get around the place.
have you seem pictures?
