You copy file want to override from the path “wp-content/plugins/hotelbookingphys/templates/frontend” to path of theme active, example path: “wp-content/themes/hotel/hotelbookingphys/” and edit it.
Ex: We want to change the title of Tour, need to edit file “wp-content/plugins/hotelbookingphys/templates/frontend/single-hotel/title.php”, we need copy file title.php to “wp-content/themes/hotel/hotelbookingphys/single-hotel/title.php”
