Question Is Shannon Worth a Stop Before Heading to Ennis?

I'm flying into Shannon for a 7-day tour that starts in Ennis. I'm wondering if Shannon is worth spending a night or two in before heading to Ennis. I've heard mixed things—some say it's a great spot to explore Irish culture and history, while others suggest it's just a transit point. Has anyone spent time in Shannon? What are the must-see spots or experiences there, or should I just head straight to Ennis?
