As you probably know, the top top floor is California Grill restaurant. Guest floors above 11 are club level (12 & 14). 11 and below are designated as "Contemporary Tower Magic Kingdom View" (opposite side of tower is "Bay Lake View"). We have stayed in rooms in the tower, with Magic Kingdom View, as well as the Garden wings (old North and South). We have stayed on floor just above Monorail as well as higher floors. We have stayed at both the Chef Mickey's end as well as the other end of the tower. Despite what you may be told, we never found a noise or vibration problem at either end nor at any floor level. Meals and Monorails do not interfere with our sleep times. YMMV. Have a great vacation.
