Hey Kelly!
The 2014 trip was before my time here at Tribe, but I don’t doubt it was a blast—thanks for the kind words about the trip this year, too. Hope all is well!
In regards to your question, at this time the only solid way to go about replacing excerpts with full content is still manually edit the template files.
To find any location where the excerpt is being used, I would recommend getting a text editor like Sublime Text—just any editor that has the common “Find in Folder” feature, which is shown in this screenshot:

If you then search for tribe_events_get_the_excerpt(), you’ll find all of the places where this function is used—which generates the excerpts.
You could then replace any instance of this:
echo tribe_events_get_the_excerpt();
with this:
echo apply_filters( 'the_content', get_the_content( get_the_ID() ) );
Here’s an example of the current version of list/single-event.php with that above modification made: https://git.io/vVKmz
Cheers,
George
