Except, this isn’t HHN. It’s not preserving anything.
The purpose of the houses were to draw attendance. The sunk cost is worth it if people are showing up for the houses. But if the vast majority of people showing up are coming despite the houses, then the expense is purely unnecessary.
Last week I heard about casting for a third house (a tent). That means that, after the first couple of weekends, the response to the houses meant that opening more could be beneficial. At least on weekends. However, when a holiday weekend that is traditionally one of the best attended days of the year is only getting 5-15 minute waits, it means more houses aren’t needed. It means their draw was short-term.
If anything, it highlights the limitations of HHN’s appeal.
