Music, laughter and hugs filled Hemisfair Park on Monday, as the city's first-ever "Kidcation" week kicked off.

The week-long event will turn San Antonio into a citywide playground.

"(We were) having fun, listening to the music, taking pictures," said 12-year-old Kayla Juarez.

Children, parents, local leaders and some of their favorite costume characters spent the day battling the hot South Texas heat but even the summer temperatures couldn’t stop them from busting a move.

"Kidcation is meant to be a lot of fun, but also put them back in the mood of learning," said San Antonio Mayor Julian Castro.

Castro, himself, even joined in on the dancing with his version of the Twist and Shout.

"I have zero musical talent, so you know, I’m just lucky I didn’t embarrass myself too much," he said.

Castro said many people helped make the end-of-summer event a reality.

"Over a hundred partners have come together to create a great experience at our museums (and) at SeaWorld and other places for our kids," Castro said.

Officials believe the weeklong event will set a new standard in the city.

They’re hopeful it will keep locals and visitors around a little longer.
