That is the short-hand. The fine print says "Views of Courtyard, Pool, Waterfall or Bay Lake," the key being the word OR. All of these rooms will have a view of at least one of these features. The outer CY views face the Villas CY and Villas Pool. Though less dramatic, it is still a quite lovely and peaceful courtyard.
To see EWP from the inner courtyard, which is most of the CY rooms, you would need to be in a lobby room (which has a straight on view of the water but is at quite a distance from the lake, these are few in number), or toward the ends of the wings over the lower CY (pool, closer to the lake), preferably the north wing. We were in that section in the south wing, and our view of the EWP was partially obstructed. If you look at a map, the beach is at the end of the north wing, and that is where the boats park to start the show. So really the EWP is not designed to be seen from the rooms.
Your best bet is to watch from the playground and beach area and then head up to bed or stay for the 10:00 fireworks in the distance.
If you are in the CY you will definitely hear the EWP music. The acoustics of the inner courtyard make it hard to ignore, even with the balcony doors
Thanks for the info!
