We believe there should be no boundaries to the Overnight experience. Guests of all abilities are welcome to join. Trained staff facilitate programming at all times.

The Overnight experience includes:

  1. Exploring Zoo grounds, which has varying smells, light, noise, and temperature levels
  2. Maneuvering on uneven terrain
  3. Spending up to 2 hours at a time outdoors
  4. Participating in both group and individual activities
  5. Moving to and from the floor or ground
  6. Utilizing public restrooms
  7. Maintaining a positive attitude and following staff instructions

Our goal is to set up all guests and staff for success. To help us provide the best possible experience, please inform us of all special considerations prior to participation. This may include information on allergies, accessibility concerns, behavioral, psychological or emotional conditions as well as any other special needs. Please contact us prior to registration at or 713-533-6739 to make an accommodation request. We are happy to work with households to make Overnights accessible to guests with varying needs. We are, however, unable to provide one-on-one support or supplementary services.
