Yeah, the ticket prices are high, but not that out of line when compared to something like a ticket to a professional sporting event. And I know that at least at Disney World (FL), the cost per day as you add days to that ticket goes down pretty quickly so that the per-day average is closer to $50 by the time you hit 5 days. Adding a “park hopper” option to go to multiple parks on the same day is a flat fee of about $55 (after tax), regardless of length of ticket - so that could be as little as $5.50/day on a (max length) 10-day ticket.
As for Disneyland, aren’t a fairly significant portion of the visitors locals on annual passes anyway? Especially on weekends?
Done the Park Hopper in Orlando as you mention big drop in average per day costs. Although the prices of those have also seen 7-8% annualized increases over the past decade or so.
