1st birthday party venue

I like to plan far in advance and I’m desperately looking for a venue for my son’s 1st birthday in August. It’s going to be excruciatingly hot so I’m preferably looking for a place that offers/allows some sort of water activity (pool, water park/splash pad, inflatable water slides, etc.)

Miramar Regional aquatic park would be the ideal venue but they are closed for renovations this whole summer 😭

I’m also thinking of doing a Western cowboy theme so anywhere that I can do pony rides is a plus. My dream would be to do it in a ranch or farm with enough space to rent a water slide because it’s too damn hot outside. (If you live in South West Ranches and would allow me to rent your property for a day I will be eternally grateful!!!)

I already checked out Davie Ranch which is perfect but way out of budget, like in the $2500+ range not including food and decor

I’m from Miami so the furthest north my guests and I would travel is Sunrise

If you have any recommendations that fit all the above, please let me know, TIA!!

ETA: I’m expecting around 30-40 guests including kids so the space needs to be able to accommodate that
