The maximum guests allowed per room is set on the Booking.com Room Details page and can be configured without first disconnecting from Sympl. However, it is important to note that your rate plan cannot be adjusted to add additional guest to a rate plan without first disconnecting from Sympl. In cases where you want to decrease the max guests value, no disconnection is necessary. Decreasing the value under Room Details will remove the occupancy level from your Rate Plan(s). Please refer to the following article which will guide you through the steps of disconnecting Sympl so that you can add an occupancy level. Changing the additional guest fee on Booking.com
Step 1: Adjust Max Guests per room value
Log into admin.booking.com and navigate to the Room Details page
Select Edit on the Room ID you want to change.
Scroll down to Bed Options and adjust the max occupancy before scrolling to the bottom to select Continue.
Step 2: Refresh your Rate Calendar
If you are decreasing the max guests value refreshing your rates calendar should result in the occupancy level(s) being removed to stop at the maximum guests you have set in Step 1.
In the example below, we have lowered our Max Guests value to 2 persons and the rate calendar reflects this after a refresh.
Step 3: Push Rates and refresh your Rate Calendar
As a final precaution, it is always recommended that you push rates and make sure that the data present on the Booking.com rates calendar matches your expectations. At any point, whether making changes in Booking.com or Sympl, you must take these final steps to review whether your changes are reflected accurately.
To push rates, navigate to the rental by clicking on it in the calendar, or from More > Rentals in the top navigation bar. Click on Rates on the left side, then on the Rate Mappings tab and choose Push All Rates.
Now refresh the browser window showing your Booking.com Rates Calendar to review.
