I think the idea is to sign up for a dining alert for the existing pre-party. Then presumably you’d get an alert when there are slots for the alert date you pick. But the open question is whether the code/url for the HEA pre-party will be exactly like the 50th anniversary pre-party. If it’s the same, setting up an alert now should work. But if it’s a separate experience that Disney puts up on the site (Ie, one entry for 50th pre-party and another entry for HEA pre-party), then an alert won’t work bc it won’t be linked to this new HEA enchanting extra option (since no one knows the link to it yet). EDIT: Apparently I misunderstood what email means too here, haha. But I do think it’s possible to set up an alert on like a res finder site, it’s just not known yet whether that will work for HEA.
