I don't really have any solution for you, I'm more in the same boat and can commiserate! Originally, our trip was scheduled for 4/15-22 with a split stay. We added an extra night to go until 4/23 at our second hotel, AKL, when I heard about the opening night, but had not heard about the previews. Same thing - not sure what to go for, especially since I'm reading the dinner packages may not be available until 5/1. My hope had been to get a dinner package or FP for opening night, even though it will be a madhouse - standby would be rough! Our scheduled AK day currently is 4/18, not one of the preview days. Not sure if I should shuffle everything? Would love to do the 4/15 preview, but that's our arrival day and it's a lot of money if anything goes wrong, plus usually go to MK on the first night. Would shuffle to do one of the other previews, but wish the park was closed to non-ticket holders like it is for 4/15...
