If you want a great place to bring the kids in Rotterdam this is it. It has it all and once you've paid in everything else is included. To name a few there's a petting zoo, a number of playgrounds, peddle go karts, a train bus, an amazing indoor play area called Grandma's place and best of all for the hot day we had, a huge swimming area with slides etc for kids to paddle and play. The water is only shin deep but bring the swimmers for the kids! Great day!
