Hi @Ralph323
As @Mike-And-Jane0 suggest, the only way to do this is to turn on Pro Tools and create a Rule Set for the scenario you want. I would suggest reading the Guides below first. Then, you would need to create a Rule Set that covers Thurs/Fri/Sat/Sun restricted check-in/checkout. Once you apply your Rule Set, be sure to check and see if it's working correctly by trying to book the dates as a guest. You should be able to restrict check-in, check-out for each day to prevent someone from booking less than a Fri/Sat/Sun. Take your time and be sure you understand how Rule Sets work. I have created a Rule Set only to find out when I tested it that it wasn't setup correctly...they can be tricky.

Rule Sets for Custom Pricing
If you plan on using Rule Sets for price changes, I would turn off instant book (if you're using it) while you test out your Rule Set. Otherwise, you might end up with a booking at a price you hadn't anticpated, as the Rule Set you created was not functioning as you thought it would. Once you can determine it's working correctly; turn Instant Book back on.
