I have been an AKV owner for about 10 years and have been affected by walking several times - mostly when trying to book concierge. In most cases, the first date or two has not been available at 8:00 a.m. at the 11 month mark. I usually grab the days I can and waitlist the days I can't get. I have been lucky every time but once, with the waitlist coming through (sometimes months later), but coming through nonetheless. Honestly, I didn't really know about walking! Now that I do, I may try it for December 2019 because we're planning to visit the week before Christmas. I don't have the stamina to start now, but I may give it a go a week or two in advance. Sure is a pain, though... and I wish I didn't have to!
