Josh Tullis knows what it's like to bring three young kids to an Ironman.

His wife ran one last year in Florida. For that race, he booked a hotel right on the beach, right on the race course.

"So we were there to cheer when my wife left for the swimming, then we played on the beach for six hours while she did the bicycle, and when we anticipated her coming back, we were out there with cowbells to cheer," he said. "And then she went and ran a marathon. So then the kids are showered, dressed for bed when we go to the finish line to cheer for her again. That's the experience that everyone expects from an Ironman. And other venues have that."

That's what Tullis was planning on when he booked a room at the Sheraton Read House in downtown Chattanooga. But the hotel accidentally double-booked more than 100 rooms and only discovered the error a couple of weeks ago.
