Two challenges:
1) I have two Custom Fields defined in the Custom Post Type – Hotel. I would like to pass the two parameters as variables (separated by a comma) into the infobox for the new Wunderground Widget.
2) There is a separate infobox for the location name in the new Wunderground Widget. As I have associated the Hotel Custom Post Type with a "Parent" Custom Post Type (Destination) I would like to populate the location name infobox with a Custom Field from the parent Destination Custom Post Type.
Could you please explain how to do this and provide an example?
