We stayed in the studio in April and I thought the layout was pretty strange. There was also very little storage space. We were (and are!) a family of 4. There was under-bed storage and some small drawers in the 2nd (i.e. non-toilet) bathroom. But my main storage spot was the coffee table, which opens up on the top, sort of like a foot locker. So everytime I wanted to get dressed, we would have to move everyone's things off.
There was one bed, a queen. The other bed was the sofa pullout. At night, this really cramped up the space, as we would have to move the coffee table to the side to accommodate the pullout. This meant that every morning we would have to put the room back together.
The two bathrooms seemed like a nice feature at first, but like Hopefully said above, there was only one toilet. So at night, when getting ready for bed, you'd have to switch bathrooms if you wanted to brush teeth, go potty, etc. The first bathroom, with the rainshower stall was very nice; however, the floor of the rainshower stall was level with the door threshold, so we always had water spilling out onto the floor. The second bathroom with the toilet was pretty functional looking, so everyone wanted to brush their teeth in the first bathroom. The other weird thing was that the second bathroom (i.e. the one with the toilet) was massive, but there was a lot of open space. Finally, both of the bathrooms had lights and fans that were hooked up to motion sensors so when anyone got up to go the bathroom, they would automatically go on.
Personally I would have preferred if they either had one bathroom, or cut into the bigger bathroom a little bit and added more storage space.
Overall however, we loved staying there. It was incredibly convenient to be able to take either the monorail or the boat over to MK whenever we wanted. It was also easy to be able to walk to the TTC. The overall vibe was really nice and it had been a lifelong dream to stay there. It just wasn't without its quirks and annoyances. I would love to stay at the Poly again, but I don't think I'd choose the studio.
