Hi Gio,
Thanks for getting in touch with us.
The Pro Add-on is $39.99 for the 3-site license and $99.95 for the Developer version.
So just to confirm that I understand what you are looking for, do you want to be able to add markers/locations to your map and classify them as either restaurants, hotels etc?
The Pro version does allow you to add unlimited markers and maps and also allows you to create your own Categories to assign them to your markers.
From the front-end, you can display a marker list and allow users to filter or search for marker locations or categories.
I hope this helps and please let me know if you have any further questions.
Kind regards,
Dylan
