Hello there!
Please be informed that the free lite version of the Hotel Booking plugin that comes with this theme works with PayPal. So it’s unnecessary to use additional plugins for website payments.
In this case, you just need to make sure the booking confirmation mode in the plugin settings under the Dashboard > Accommodation > Settings is switched to “Confirmation upon payment” and the PayPal payment gateway is enabled and configured under the Dashboard > Accommodation > Settings > Payment Gateways tab > PayPal subtab.
