Booking System Not showing On page

Hi,
I have support access on for allaccessiblefloridatravel.com. There is a booking embed script that is on this page:
https://allaccessiblefloridatravel.com/booking/

The client is reporting that he is not seeing it. ARe you able to see it? What oculd be causing him not to see it? It is using the Travelpayouts plugin that is on the site. I used the script option.
