compatibility with other theme

Hello there! 

Thank you for your question. 

Please be informed that “Carmelina” is a third-party theme that doesn’t use our Hotel Booking plugin. It uses a third-party booking solution we’re unaware of. But if you’re asking whether you may use our Hotel Booking plugin on this theme, please be informed that our Hotel Booking plugin doesn’t provide any default styles or design, it inherits everything from the active theme. So it may be necessary to apply some custom styles to make all plugin sections and forms look beautiful on the third-party theme that hasn’t been designed for the plugin, like the theme you’re referring to.
