Yes, Martinique is very close to the main building. Half of Martinique is preferred. If you look at the map in the link below, the letter B marks Old Port Royale which is where the food court, gift shop and arcade are located. The letter C is the main feature pool. As you can see, Martinique is right next to both of them.

Awesome - thank you so much for your help! This is just what I was looking for! Now getting excited for November. When we were there last summer it was too hot to explore. This will be a great opportunity to really see the resort.
Thanks again!
