Make sure you are wait listed and call every day too -
We are trying to upgrade to 1 bedroom for June. When we booked at the 11 month mark a studio for 7 days sounded doable now I am wishing I had the 1 bedroom and its not available for all 7 days so I keep calling looking for a cancelation. They said its a 50/50 chance - just no history on room reservations GVC is too new.
