Cart/Checkout

Hello,

I am using the latest version of WP Hotel Booking on Vantage premium theme, and I am trying to make a list of hotels to book but when I put the rooms and go into the page there is no checkout button I tried using this short code [hotel_booking_checkout] but instead of putting a button to redirect to the checkout page it just puts the page itself on the room page, and I couldn’t add the cart icon on menu …
same for availability I need them on the same page of my room. is it possible ?
Any clear tutorial for this ?

Thank you
