• Grippy socks required for everyone in the play zones, sold at the desk if you forget them
• Adults stay out of the big-kid zone: ages 3 to 8 play with staff watching, while the baby zone for 0 to 2 takes one adult per child
• ID needed at check-in: the adult who registers the kids shows a DNI or passport and is the only one who can collect them

CaSa Color is an indoor play space built around a big wooden play house on stilts. Kids climb up by ladders and climbing ramps, cross bridges between the little houses and slide down from the terraces into a ball pool below. Around it sit motor-skill zones with tunnels, climbing walls and ride-on toys, a separate baby area for under-2s, and a café where parents wait.
