@Mike-And-Jane0 We have a Balloon Fiesta here in October for which everyone raises prices for about 2 weeks. There used to be a button where you could set custom pricing for specific date ranges. I don't see that anymore. And the feature you mention on the calendar when you highlight specific dates is also not showing up on my screen. Wondering if anyone else has a solution or is seeing the same issue.
You can apply a ruleset on year 2022 (or any other desired time period) to increase or decrease rates by a percentage set by you. BTW It does not work if Smart Pricing is active during the choosen time period.
