I set a no-review holiday, but I mistakenly had the "move existing reviews" checkbox enabled. Now I have a crazy number of reviews the day after the holiday.
There is not, sorry. It would have only moved the reviews off of that one holiday, so you should not have more than 2 days of reviews on that day; the longer the holidays stay in place, the more normalized the numbers will be.
It's mainly 2 large (2000+) word schedules that are a problem. I'll freeze each of them to clear the other in succession. I think that should work to get back to normal without melting my brain.
