Historically, HHN has started selling tickets even before they announce anything. The tickets sales start strictly with the website update/aesthetics reveal or with the announcement of a biggest IP.
VelociCoaster is the primary focus. They want people planning summer trips to ride their new jewel. Announcing anything big (and especially selling tickets) prior to the summer window “closing” runs counter to that strategy, as it incentivizes guests to wait until the fall to come.
We will likely see tickets go on sale the end of June, with the announcement that Bride and Tooth are returning plus a second IP (likely Hill House, but maybe TCM). From there, they’ll maintain the push for packages through August (8 weeks), with likely weekly to bi-weekly announcements.
