So today, finally, my patience came to an end. I called Disney and accepted no nonsense and insisted on speaking to someone who could resolve this today. Turns out, the first person I'd gotten days ago had given me the wrong activation code. The website noted it as a club id problem, though, so she couldn't figure it out. That's what I get for staying patiently on the phone with someone whose accent was so thick we could barely understand each other.
So I was finally able to create and activate my online account. Points are showing up and I ran a check of available rooms for march as a dry run to familiarize myself with the system. Seems easy enough.
So my timeline from submitting to ROFR until today when I'm really in there and could book: 5/21 to 8/2.
