If Boutique is running a campaign you want to join, you can easily opt-in your property edit page. To get started, go to Properties and select the listing you wish to edit. From there, scroll down on the sidebar menu (beneath your property photo on the left), and click “Promotions.”
Here, you can review the campaign details and select the promotions you'd like to participate in. Please note that once the promotion begins, you won't be able to opt out.
