MattMatts-Momma - Welcome! I'm glad you are enjoying the thread.

Try not to let the GF info overwhelm you, if you have any questions, just ask.
Yes, all the balconies on the top floor of SL are enclosed (dormer) balconies - other than maybe the suites. If you look at the photos in post #214 above, you can see in the first photo the pool side of SL (it is the building in the center of the photo). You can also see the marina side in the 4th & 6th photos, through the trees, across the marina - the dormer rooms have little pointed roofs on them.
Some of the balconies on the 3rd floor are also enclosed, and they are on the ends, so if you want a regular balcony
and an end room, I would request 2nd floor. Unfortunately, that could mean you will end up on the pool side, as the number of end rooms on any floor are limited (to 4, of course, lol). I think pool side is the most-requested, though, so I'll keep my fingers crossed for you.
You might like the dormer rooms, some guests do. Here is a link to page 45 of the previous FAQ -
gilsan posted some lovely photos of a dormer room in Big Pine Key (scroll down to post #669):
