Botched = underestimating. I guess more specifically, what was botched was that they never made the managemental call to not limit the availability to those with reservations within a certain time frame (30-60 days) and seeing how demand goes. As it was, there were people here who ordered on day 1 who didn't have check-in dates until mid-2020. That's nearly a year's worth of resort guests.
All the more reason shop Disney has stock but MDE didn't? One word—discount. IMO and prob others, buying a magic band at $25-30/ea for a short trip—say for a family of 4—gets expensive, given you get one that does the exact same thing for free. But for a ten-spot? Yea, that's a price point that makes it more manageable. So of course there will be a swell of demand, besides....when does Disney discount ANYTHING?
They can't even keep new popcorn buckets in stock. They have to limit new merchandise items so people don't snap them up and sell them on eBay. So of course I can agree they 'botched' this and underestimated demand, or didn't put stop-gaps in place, just knowing the history of the 'new anything' frenzy caused by the Disney community. Rolling them out in waves would have allowed them to assess and restock accordingly.
