Looking for a plugin for daily admission sales

I’m looking for a plugin to help our nonprofit science center with a very specific job.

We have daily admission tickets that we sell online, but it’s on Wix and I am transitioning our site to WordPress. Unfortunately, I’ve been unable to find anything to serve our needs for the online daily admission tix.

I need to be able to have a calendar and ONLY sell tickets on specific days, since we are only open some of the week. I don’t need to limit ticket sales, I just need to make sure that people are not purchasing admission tickets for a day that we are not actually open. So having the calendar will enable me to make sure that I have only provided tickets for the days we are actually OPEN.

THEN to make it more complicated, there is one day a week (first Saturday) that our admission is only $1. I need to be able to set those days specifically at that price. But ONLY those specific dates! I’m ok if I have to go in and manually add those because it’s just 12 a year and not a huge deal. The rest I’d like to be able to set and forget. Although I would also really like to be able to go in and manually close tickets when we suddenly find we need to close unexpectedly (power outage or planned construction or whatever comes up). So it would be nice to be able to go in and edit the dates as needed.

Bonus if this plugin has the ability to scan a QR code on arrival to check people in.
