Bill laid out the facts really clear about what can be seen.
In my opinion, **the best thing about theme park view is that you can watch the fireworks from the privacy of your own balcony**. You can have the Wishes music piped in through a channel on the TV. If you don't plan on doing this, in my opinion, the room view is not necessarily important.
Yes, it's nice to be able to see the Castle and some of the park lit up at night, you can see the monorails going by. We were able to see the Water Pageant off in the distance in Seven Seas Lagoon. But, if we were not watching the fireworks, I would have just gotten a regular room, and then went upstairs. I think any
DVC member staying on points at BLT can head up to TOTWL and watch the fireworks from there too.
