We've been members for four years now, six trips, always in a studio for the 2 of us. I'm completely comfortable with the studio. Sure...it's a glorified hotel room...nothing wrong with that! I'm on vacation, I don't do laundry. I can pack one suitcase for a 14 day trip and not do any laundry. I don't cook when I'm on vacation, either. The microwave, toaster and fridge are PERFECT for my needs. Mainly for chilling and reheating leftovers and storing sodas/waters, plus the occasional toasted bagel. We use a full-size bed at home, so the studio bed seems big to us.
I've visited friends who were in one-bedrooms, and most of the space seems wasted, particularly the full kitchen. I think the jacuzzi tub might be a fun splurge, and the laundry might be convenient, but I'd only use both once or twice on the entire trip.
We usually are out by 8am and back around midnight every day of the trip, so the extra space is a waste. As long as there aren't suitcases on the floor, (we store them in the closet), or bags of Disney merchandise piled in the corners (they go in the closet, too), or toiletries all over the sink counter (they fit in the drawers and cupboards underneath) I'm happy.
I would actually like not having the TV, we never turn it on during the entire vacation!
