We’ve been hearing that hemorrhaging customers thing for 3+ decades of complaining now and guess what- it hasn’t happened. The parks are still full to capacity.
The reality is, there has always been some group of guests who reach their breaking point for any number of reasons and say they’ll never come back again. And there is another (often larger) group right behind taking up their space.
If you’re unhappy with the changes (which is your right) then you have the choice to spend your vacation dollars somewhere else. But the reality is, the growth in the parks has continued decade after decade, despite a regular wave of people who are ‘done with it’ over one thing or another.
