Thank you for your kind words!
If I understand correctly, then you want to create separate taxonomy filters, but all of the items you want to display in the filters is from from the product category taxonomy. That's unfortunately not possible, because the filters can only be grouped by their taxonomy.
A possible solution is creating two separate taxonomies for the “Destination” and the “Type” as well, so they will be logically separated from product categories, and the plugin will display them in a separate filter box as well.
