Renting an ENTIRE Waterpark for my 40th Birthday

For my 40th birthday, I wanted to do something fun.

So I rented out America’s largest indoor waterpark.

It was great fun. Honestly, it was like a dream. I was so happy.

Here are some of my favorite photos.

Favorite Photos

Her first water slide ever! Courtney didn’t make the group photo, but I promised I would include her in this blog recap.

This was a crowd favorite. Pretty easy, and lots of fun. L to R is: me, Michael, Mirza, and my father.

This tube ride was a little scary and a lot of fun! Zach, Clay, Aaron, and Will.

Aaron stayed at the park the longest, from 8AM to 5PM. Most of us left around 11AM.

This Flowrider surf machine was my favorite! I am very happy to be on this ride on my birthday.

Event Information

When: December 8th, 2021

Where: Kalahari Resorts Waterpark in Round Rock, Texas

Who: 30 of my Austin friends. I think there were more staff and lifeguards than attendees 😅

I love doing crazy birthday parties — look what I did for my 36th birthday at the Metropolitan Museum of Art. SUMMER CAMP!

My parents even came for my birthday! My mother took a bunch of photos, and my father rode all the rides with us.

We got so many good photos of Sam. This is one of my favorites.

Flowrider Surfing Photos

Usually there is a 20-minute wait to get time on this surf ride.

Then you can only surf for 30 or 60 seconds. Or less if you fall off.

But there were no lines for my birthday! People got in a LOT of practice time.

Zach was a natural. Probably from all of his wakeboard experience.

Neville perfected this trick that he called “The Magic Carpet.”

Sam even managed to stand up and surf for a while! This is much harder than the boogie board.

This is peak male performance. I could ride this thing all day!

Thai Massage and AcroYoga

There’s a risk of injury with old people (like me) and waterparks.

So I hired my favorite masseuse, Rachel, to give Thai massages on-site.

Rachel brought her own Thai floor mat and gave my friends massages for any sore areas during the party.

My friend Jason Nemer is also an expert at Acroyoga. He invented it!

Jason volunteered to fly some people and help release any waterslide tension.

Lessons Learned and Conclusion

This was so much fun!

Some things I learned:

  • It was way less expensive than you’d think (under $10k).
  • I paid $500 extra to have the wave pool opened up. Nobody used it.
  • We could either do the buyout before opening hours (8AM-10AM), or after it was closed (9PM to midnight). I’m glad we did it in the morning. It was a big ask to get people to wake up so early, but everyone was so full of energy and happy.
  • I am glad that Rachel, the masseuse, was there. She was busy the whole time and everyone loved her.
  • I hired a DJ through the venue (around $300) and he played 80s and 90s hip hop. Very good and fun.
  • I moved to Austin less than a year ago from New York City. It is wild to think how many new friends I’ve made. Most all of them have come from me hosting my small cocktail parties.
  • Do you want to make more friends in your town? Or learn how to “network” and boost your career without it feeling gross? I wrote a how-to guide about what has worked for me, check it out here (called “The 2-Hour Cocktail Party”).

In conclusion, I’m happy that I have so many crazy friends who would join me early on a Wednesday morning to ride water slides.

Life is about the memories we make! This will be an excellent memory.
