We stayed in room 5441 for our honeymoon. This is in the Sago Cay building and we had a great view of the castle. Conch Key also has great views of the castle. I think Boca Chica has great views of not only the castle, but the whole lagoon, including the Contemporary and the Polynesian. There are some lagoon view rooms that do NOT face the castle...they just face the wedding pavillion and the Polynesian. Even if you book lagoon view you are NOT guaranteed a view of the castle. But it's worth it to take the chance, in my opinion. Hope this helps.
