We just got back from staying a week in the Marina (Magic) Tower.
I was hoping for the Dreams Tower from what everyone was saying here, but I was pleasantly happy with our location. We liked being in the tower with the lobby and were centrally located by the pool and the walkway to Downtown Disney and the parks. We were on the 8th floor and yes, had a view of the parking lot, but also DL and the mountains. We could see the castle, Splash Mtn., The Matterhorn. We watched the fireworks one night from our beds! The sunrise over the mountains in the morning was beautiful.
We were very satisfied with our location.
