the DD disney hotels
www.downtowndisneyhotels.com - you only want the ones with a clear view...
I found the Polyn's Tahiti (which is not concierge) has the best view from my room - straight across to the castle.
you need to be careful with Polyn many of their very, very expensive rooms don't get a view of the castle because of that island....
with the Cont any room on the MK side (seven seas lagoon) the problem here is those are expensive. the Bay lake side has the same rooms for less money - and there is a 4th floor overlook that anyone can watch the fireworks from. (they don't allow the 14th anymore - this is just for restuarant guest)
I don't participate like the GF....
from the Cbr and Pop you can see the Epcot fireworks. the Pop can also see some of the Studio fireworks....
of course from the Epcots resorts you can definitely see the fireworks - BC/YC/BCV, BW, D/S - from the right room....
even some of the higher up houses in the area - you can see the fireworks...
Orange Lake has reported higher fireworks, Silver Lake definitely,
