I guess you are right. Maybe this is Disney's way to begin to reign in the unofficial events?That's pretty much exactly what Dapper Days is. And they even say "dapper duds," which is pulled from Dapper Days as well. DD certainly doesn't own that term, but it seems funny to suddenly have essentially the same theme 10 days before the long-planned Dapper Days event.
either way, I hope themed days continue in the parks, I enjoy them. Still hoping someone might be a little extra generous and offer to register my wife and I for this event. Our pass expiration date seems to fall inbetween the dates they offer these events for. Might be too crowded anyway, but seemed like fun. It's too bad Disney doesn't offer the events for all passport expiration dates. Maybe an advantage to buying an AP at certain times of the year then.
