Activities for toddlers

I’m excited to be visiting Houston for the first time next week with my husband and our twin toddlers (18 months old). We live in New Zealand, but Houston is somewhere we’ve always wanted to visit – so excited we can fly in direct there.

We’ve been making a bit of an itinerary for our time in Houston, but it’s always good if we can include an activity into the day that will tire the twins out! Just wanted to check if anyone could recommend any good activities for families with young kids, or places that are popular with toddlers that we should consider? We will be in Houston for 3 days, and will have a car. Thanks so much!
