As much as I hate to say so. I think the situation is vice versa. Increasing amount of hotel/romance builds is not due to "insider" information on upcoming pack. But because of the amount of speculations/wish lists about this topic. For sure top content creators pay attention to what's popular now. And since everybody's speculating about hotels/weddings they start to center their content/builds around it. And then their followers pick this as a hint and that spirals to the expectations hype. So I'm always very skeptical to these assumptions.
That said Romance pack would be a great thing to have! Though my personal #1 would still be generations.
