My thoughts exactly, like Canobie Lake Park is one of my favorites in New Hampshire, Id imagine they're a "larger" local park, but Im worried for them. I think they opened this year, I did not go, and Id be hesitant to go next summer but its too early to state that either way. Its park like those, which were my first exposure to an amusement/theme park, that I worry about surviving and the way you described it is perfectly showing how it affects more local parks due to economic reasons, compared to the people who travel to UOR or WDW. Big difference in consumer base, which again, is worrisome for the local parks.
For UOR and WDW, they both have projects being worked on for 2021/2022, I don't think anything past those dates, and it wouldn't shock me if we didn't see ground breaking being worked on for ANY new projects until 2023, may be totally off but in my head Ive assumed nothing new in Orlando for 3-4 years after 2021/2022. We've been spoiled in Orlando theme parks since 2010 like crazy, and were promised pre-covid for even more development for these parks. Its gonna be a striking change of pace I think for some, but its a pace I'm expecting at this point.
