Ok to settle a few things.
This is DLP's castle, It looks nothing like the WDW castle which is in the advert
This is WDW's castle, the one in the advert
It is NOT the DLP hotel as this would give you a view of Main Street towards the castle, and the rooms do not look like this, as i've stayed there.
This is the view from the Contempary, Space Mountain will not block your view and the Contempary is not far from the MK it is just across from the Bus stop of the MK within walking distance. I have also stayed in a MK view contempary room and this is the view you get. You can even hear the wolf howl from the Haunted Mansion at night from the Contmepary and the Grand Floridian, although the Grand Flordian is further than the Contempary
So as i said i think the room is a set but the view is real, Stay in the Contempary and you'll see. Its great because if you get the right room you can watch the fireworks over the castle from your
bed and can fall asleep watching the castle change colours which is my favourite memory of WDW.
