Cedar Fair (FUN -0.76%) reported second-quarter earnings this morning that showed attendance at their reopened amusement park venues was lower than expected.

All of its parks were shut down in March as the COVID-19 outbreak spread, but it began reopening some of them late in the quarter as it was able. Instead of the 827 operating days across its parks it expected, or even the 726 days it had last year, Cedar Fair had just 39 operating days. Attendance plummeted by 8 million visitors as people did not show up in the numbers it anticipated.

The theme park operator suggested the timing of its reopenings coincided with a rise in COVID-19 cases, leading people to avoid coming out.

The no-fun zone

Revenue for Cedar Fair all but evaporated during the second quarter, plunging 98% to just $7 million from $436 million last year. That resulted in an operating loss of $142 million compared to an operating profit of $102 million in 2019, though it was offset by a steep decline in operating expenses. Net losses came in at $133 million, or $2.35 per share.

It's not alone with its dismal parks showing. Walt Disney (DIS -1.01%) reported a rare loss under generally accepted accounting principles (GAAP) of $2.61 per share, though on an adjusted basis, it managed to post an $0.08 per share profit.

On its earnings conference call, Disney CEO Bob Chapek said rising coronavirus cases sparked "trepidation" in travelers, leading to "higher than expected" levels of cancellations.
