Hi Xavier, Tina.
Most of what you are asking about is definitely possible – first of all please familiarize yourselves with our Themer’s Guide and this tutorial on template overrides.
To remove links to the venue page you would basically look for this template tag (in your custom single.php template):
tribe_get_venue_link( get_the_ID(), class_exists( 'TribeEventsPro' ) );
If you only want to include the venue name, completely unlinked, you should be able to replace the above code with something like this:
echo tribe_get_venue();
Further permutations are of course possible. A guide to our template tags and other functions is available in the form of our technical documentation – so that’s another great place to do some research about what’s possible.
