@Trish---Duke-The-Pug--an0 Hi there! Yes, you can set minimum night stays for Saturday requests! Go to your calendar and to the right click on Availability Settings. There you can set a minimum night stay for specific dates. I've set 3 night minimums for major holidays: Memorial Day, 4th of July, etc.
With regards to local taxes, I agree 110% with you! I'm in the same boat...I choose to incorporate in my nightly fee too which causes the tax to be higher and my Airbnb fee as well. It would seem to be easy to do...just let the hosts put in the percentage required and presto! Done!
So hopefully this will help....and no more Airbnb jail!
