We passed ROFR on a Friday (2/4) and I received my closing documents from Magic Vacation Title the Tuesday (2/8) after. I was delayed in returning my documents due to financing issues, but they received them on a Friday (2/18)and I closed the following Tuesday (2/22).
I was told I would be in the Disney system in 5-10 business days. I called yesterday and am not in the system yet. Even if I wasn't delayed by financing issues it would still have been 2-3 weeks after passing ROFR before actually getting in the Disney system.
Disney may have a bit of a backlog given the recent boom in the resale market.
