Martinique 21 isn't near either the main pool or quiet pool, so I'm assuming it would be a view of the lake. It does look like one corner of the building would have a view of the lake, though, so I'm assuming you'd be in that part of the building closest to the lake.
Since your trip is so far away, how are they able to let you know NOW that you'll be in Martinique 21? Or was this just what you have requested?? I'm really curious! LOL
