Where are you located?

What is your child to adult ratio policy?

We allow 2 adults per 1 child. If more than two adults need to accompany the child, an additional charge will apply.

What ages are best for Dino Discovery play?

We recommend ages 1-8 but we won’t turn away a kiddo who wants to play!

**Little dinos under 1 year are free when accompanied by a paid sibling**

How do you keep the center clean with so many kiddos having fun all day?

Our play sessions are 90 minutes and we reserve 30 minutes between each session to clean, put toys away, and make sure all of the farm animals go back to their homes.

How far out can I schedule a birthday party?

We are currently scheduling birthday parties through December! Schedule your birthday party HERE!

Can I rent out the center even if it isn't for a birthday party?

Absolutely! Please call us to inquire about renting the center out. (509) 827-1471

Can we schedule playtime on the weekends?

Yes! Birthday parties take priority on the weekends, however, Saturday and Sunday playdates will open up on the preceding Monday for reservations for times that birthday parties are not scheduled.

Can you tell me more about 123 Rex & Me (mommy & me)?

Our Mommy & Me playtime is for ages 0-2. We have age-appropriate activities to help the littlest of Dinos thrive and learn at their own pace.

Any adult can bring a child, not just mom 🙂

Dino discovery is wonderful! Tri cities has so much going on but not much catered towards the kiddos for indoor activities, we will definitely be back. The reservation idea is great as well we are able to play with out tooo many friends running around. And the snack at the end 10/10 my little Dino is always hungry right it after playing a while so this is the perfect way to end our play date!

⭐️⭐️⭐️⭐️⭐️ Every detail has been thoughtfully put together. Educational, fun, inviting and warm this is exactly what Tri-Cities has been needing for our kids and it is here at Dino Discovery! Signing up for the membership without question; thankful for the cultivation of imagination and play that is being brought to life for our little ones.

We had the best playdate at this cute place!! The best variety of playtime for all ages! We loved that they limited the amount of kids per play period . My toddler loved all the imaginative play as well as the fun slide and then the coloring table! They truly have something for every kid! We can’t wait to come back!!!!

Socks are required for ALL attendees – kiddos and adults. Thank you! 🙂
