My article introduces the dates, times and geography, then links to the official web site for the specific details.
Update: the Beach Studio Tour of Fall 2013
The details change each season for this semi-annual art tour, so it's worth checking.
By the way, this writing tip still is true; especially as their official site does a fine job of explaining what's on. My big job is simply inviting readers to check them out.
One Specific Writing Tip
The specific problem here is that there are 15 venues, 8 genres and 25 individual artists. It's painful to highlight a few, and redundant to copy all the information from the official site.
It was a different situation with "The 2013 Khalsa Day Parade in Toronto long after Vaisakhi", because there was no one official web site and details were sparse. I dug into the reference material and presented the most cogent guide to this annual Sikh New Year parade in Toronto. (At least, I think it's the best summary).
My specific writing tip for situations where the many details are already well handled by an official site is to let that site handle the minute details.
Concentrate on the big picture. I explained where the core of the Toronto Beach Art Studio Tour would be, and how many venues were outside those boundaries. I also included the dates and times, since that was a short paragraph.
You should do likewise. You might focus on one or two details that make the event interesting, or the "must-see" aspect of a tourist destination.
But unless you're comparing two products feature by feature, you don't need to list every detail.
Make art, not checklists; at least if you're covering a wide-ranging event like the Toronto Beach Art Studio tour.
