When you check into the Studio- let them know you'd appreciate having your 1BR available when you have to move if at all possible. They will note your request, but won't (can't) guarantee anything.
The day before you'll be moving, again go to the front desk and reiterate your request. With a LARGE smile on your face, let them know that you'd appreciate being homeless for as short a time as possible. They will note your request, but won't (can't) guarantee anything.
On moving day, go down to the desk around 9am and again (with a BIG smile on your face and a twinkle in your eye) let them know how you'd appreciate their help with getting you a room as quickly as possible.
With any luck at all (don't forget that winning SMILE!), you'll have a 1BR ready to go to before 11am- and you can easily get moved with minimal inconvenience.
If not, be assured you gave it your best try and there is nothing ready for you at 11am. Just allow the Bell staff to store your bags and enjoy time in the park until that room is ready. (I'm betting you'll have it before 11!)
Enjoy!
