Hello
I checked the code and see nothing weird. Then i move to check wpml setting and see you did not select Translate Option for Room Parent so theme does not save new Hotel location in other language that room belong to and then room location can not save.
My image will show you more details and please check again.
Also you should not change your rating after each theme problem. We need time to check for your problem and help you fix it. Just wait for our response with your issue.
Thanks
