We currently have a fixed amount surcharge for additional guest fees with the multiplier set to every 1 guest above 2 up to the property max. I’d like to have an additional guest fee for every guest over the first 2, where each additional guest would add another 5% of the initial rate to the final total. For example, if there are 4 guests and the initial rate is $100 per night, the final rate would come to $110 per night. If the initial rate is $200 per night with 4 guests, the final rate would come to $220 per night.
I'm not sure if this is a glitch or a feature, but whenever I switch the amount type to "percent of rent," the multiplier fields just *disappear* as soon as that option is toggled. I've been able to get the multiplier fields to temporarily reappear after selecting the "percent of rent" option by selecting a different surcharge category and then switching back to "Additional Guest Fee," but I still get an error stating "You must select a Multiplier for Additional Guest Fees" when I hit the save button.
As a test, I've also tried using the "booking fields" section to set booking criteria that state the percent-based surcharge should be applied to any bookings with more than 2 guests, but I still get the missing multiplier error when attempting to save.
Our current fixed amount rule plays nice with our Airbnb integration. I understand that a "per night" application for a percent of a booking's total rent wouldn't really make mathematical sense otherwise, but it appears that the only way to get additional guest fees to push to Airbnb is to ensure they're set to that option – which also disappears when the "percent of rent" amount type is selected.
The OwnerRez support article on surcharges seems to show that we should be able to create an additional guest fee based on a percent of rent, but I'm at a total loss as to how this might be accomplished without being able to set any rules for when the surcharge should apply via either multiplier settings or booking criteria.
• Is there any way to achieve the surcharge scenario I described above?
• Despite the mathematical redundancy, why can't a percent-based charge be applied per night as opposed to only per stay?
• Is there any way to create a surcharge like the one above that will play nice with Airbnb?
The support articles and forum threads I've been able to find don't appear to have clear answers to these questions.
