If Iron Gwazi opens in 2022, I'd be pretty damn angry. I bought an annual pass with the expectation of riding this year, because that's what Busch Gardens keeps saying. COVID cases are going down, more people are getting vaccinated, restrictions are lifting. There's no reason not to open it this summer other than lack of international tourists, but places across the US are opening rides anyways so that reasoning kinda sucks.
If you're going to delay it, just announce it already. Don't drag this out for another six months.
I would doubt they will keep people waiting this long. But recovery from COVID and the recent job fairs, and signs of tourism returning to normal are something to highlight. Things will get better.
