Nazran,
While we stay at the Polynesian everytime we go to WDW, we don't need a MK view room to enjoy view. Having dinner or breakfast at 'Ohana, hanging out @ the volcano, Electrical Water Pageant and Wishes, going to and from our room is enough for us. Once we get to our room - I'm shot for the day! We had a MK view during a long weekend and it was awesome at first, but we were not in the room enough to justify the $$$$$ for the room. Sometime in the future when we are going to kick back at the Poly and take a break from the parks it will be a different story...
