We put 7 people in a 2 bedroom with one being a 4 year old. I can't imagine having 10 people in that same villa. It will be tight.
We had no storage issues in the master bedroom - the closet is huge plus you get the dresser.
My 2 teens slept in the living room area, and they had issues with where to keep their clothes. Since the pull down bed takes up all of the space in the dresser, the storage options are limited. They each had the space inside a small square ottoman, and they each had one drawer in the divider between the kitchen and living area. They also shared the small linen closet in the hallway for their hanging clothes. If you have 3 people in the living room, storage will be even tighter.
We had a dedicated 2 bedroom, so my 3 guests in the 2nd bedroom shared the dresser under the TV and the medium size closet. If you have a lock-out, you lose the dresser. I also don't know how the size of the closet is affected with a regular studio since the kitchenette portion of the studio will have to take up some of the extra space that a normal 2nd bedroom would have. If you have 5 guests in that studio, you will have storage issues.
