Hawaii longhouse has 54 lagoon view rooms on 3 floors. The Concierge will be moved over to Tahiti for a few months starting in June while Hawaii is refurbished. When in Tahiti it will have 69 lagoon view rooms.
As far as Hawaii longhouse is concerned the view situation is:
1501 is down next to the lounge and the view of the castle is partly blocked by palms on the beach.
1502 is also partly blocked by palms
1503 is partly blocked by beach palms
1504 is slightly blocked by beach palms
1505 is clear to the castle
1506 is blocked by palms on the grass in front of the longhouse.
1507 is clear with a good view
1508 is slightly blocked by palms on grass
1509 is slightly blocked by palms on the grass
1510 is a good view
1511 is a good view
1512 is a good view
1513 trees on the path block view of lagoon and castle
1514 trees block view of lagoon and castle
1515 trees partly block view on the left
1516 good view
1517 good view
1518 (last lagoon view room) slightly covered by foliage on the right but has a view of the lagoon and castle.
These are all looking from the ground level but some of the partly blocked views are the same on the upper levels. The other thing I will say is that even a partly blocked view (which everyone stays away from) is still a great view. I would not consider any of the lagoon views horrible but some are better than others.
Here is a link to our view from 1505.
