no one on the boards here can answer that question for you.
the TM's at check in would be the ones that have that information in their system.
if foliage is cut, trimmed or removed, that room may no longer have a blocked view.
What has been an obstructed view in the past, may no longer be so.
and with that, if trees have grown and branches sprouted, you might have a new room to be listed as limited view.
it varies a lot when a room has an obstructed view between the past, and now.
the rooms that have the views of only a rooftop, is a different matter.
that won't be changing.
