The rooms in Boca Chica- lagoon side, to me, seem to have the most "comprehensive" views... comprehensive because you can pretty much view the entire lagoon area- you can see the MK off to the left (if standing on the balcony), Contemporary directly in front of you, Poly off to the right... The MK fireworks and Electric Light Pageant are readily viewed from these rooms. Downside-- we hear noise from the MK (train whistle, primarily!)... but you kind of expect that when you're staying in a room facing the park! Maybe that's part of the magic!!! But, the views are pretty nice. And on a really nice day, you can open the balcony doors and enjoy the sounds of the lagoon and get a nice breeze blowing in. It was nice, too, to be able to watch family members riding the SeaRaycers on the lagoon while a child was napping.
For a quite, but nice view, the rooms on the lagoon side of Big Pine. You just have the beach and a view of the Poly and Wedding Chapel- not really interesting, but it's pleasant!
