I just want to say that going to sleep with the castle in sight and greeting you as you start the day is wonderful and being able to see the fireworks from your balcony is also magical!
Don't know what your paying a night but you may want to compare it to the rate of the lagoon view in the concierge building. There is much more to enjoy in my opinion. Not all rooms are guaranteed an unobstructed view but you have a pretty good chance at being able to see something and then you have th added pleasure of breakfast, snacks through out the day and great appetizers at night and more. Not to mention the great staff that really try to make your stay as pleasant as possible.
Just a suggestion
