Multiplier error?

I'm trying to add an add'l guest fee when there are more than 6 guests.  There is no "Multiplier" listed for me to correct.

It looks like the format has changed a bit from the old help files... https://www.ownerrez.com/support/articles/common-surcharge-discounts

So what am I doing wrong?

This is happening because the "percent of rent" amount type is selected, which can't be multiplied.

Switch to the "fixed amount" type and then you'll be able to select the multiplier.

But I want to choose a percentage.  So why is it giving me the error if a percentage type doesn't use a multiplier?

Per-guest fees must be flat amounts because of how they are sent to channels.

If you're trying to create a percentage fee that kicks in once for more than 6 guests you could do that but you'd need to pick a different category. Also, that sort of configuration will only work for direct and Vrbo bookings, not Airbnb. Airbnb only supports per-guest flat amount type guest fees.

My goal is to give people a realistic estimate of costs.  It's a property that can be split in half, up to 6 guests or both halves up to 12.  When they put 12 in, I don't want them to think it's the pricing shown (only for half).  What's the best way to categorize that if not guest fees?

There's not a good way to represent pricing that different with guest fees -- those are meant for properties where there's an incremental charge per guest as you add more. If the same for the first 6, and then doubles at 7, the way to do that is with multiple properties.

Can each half be rented separately, i.e. can two groups of 6 guests rent at the same time? If so, the best thing to do is to set it up as three properties with mutual blocking (half A, half B, and the whole property): https://www.ownerrez.com/support/articles/combined-properties-blockoff-lockoff

Or, if you can rent half or whole but not both halves at the same time, then still use mutual blocking but with two properties -- one for the half, one for the whole.
