Most towers range from 1 to 2 kilometers in height, either hanging from the ceiling or protruding from the bottom of the ship's interior. Considering you're in a hanging tower, and there's about a mile in between each tower, you'd need some sort of flying mechanism, or the ability to fly, to get to another tower effectively. That, or somehow activate the shuttle system that links your tower to another.
If you choose to fly, you'd have to deal with the numerous drones placed in the ship's interior walls, along towers, etc, that actively target specific entities they locate. It'd be quite a lot of eyes on you if you choose to fly.
There are 280 towers in total.
