Looks like I am not very lucky with many parts of the theme. I am now working on setting up all the rooms.
The Image Gallery is not saving the images and the Additional packages that I created in the “Extra Options” section are also not being saved after being added to the room.
The Moteling demo theme also shows many icons that can be used for room features. However, they are not available. This is not important to me but I wanted to mention it.
