Preparing for Park Opening: Little Things that Make a Big Difference
ADG has helped bring hundreds of waterparks to life, and with that comes a lot of lessons you will not find in a quick Google search. As more parks gear up to open in the coming months, we thought it would be helpful to talk about one of the most important and often overlooked parts of preparing for opening day: the little things.
Not the big, obvious checklist items, but the small details that do not always make it into manuals. The things that seem minor in the moment but can have a huge impact on safety, preparedness, and the overall guest experience. For those who have been in the industry for decades, some of this may feel like second nature. But it is just as important that we are setting up the next generation for success, and reminding ourselves that the tedious or seemingly minuscule things are often the ones that matter most.
The Things You Don’t Notice (Until You Do)
A lot of the best preseason prep does not come from a checklist. It comes from perspective.
One simple exercise we have seen make a big difference is walking your park like a guest would. And not just a casual walk. Push a stroller, carry a bag, bring kids along if you can. Suddenly, things you have passed by a hundred times stand out. A tight turn. A slight slope. A transition in pavement that is just uneven enough to be a tripping hazard.
These are not the kinds of issues that jump out during a standard inspection, but they are exactly the kinds of things guests remember.
Winter Leaves Clues Behind
After a long winter, concrete may have shifted in ways that are not immediately obvious. A small heave here, a hairline crack there. Nothing major at first glance, but enough to cause problems once the park is full and moving. The same goes for tile. A single popped tile in a pool, especially the small ones, can create a sharp edge that is hard to spot but easy to feel.
It is rarely one big, obvious issue. It is a collection of small ones that add up if they are missed.
The Equipment You Trust Most
Pumps, gauges, and systems tend to fall into the category of we will know if something is wrong, but that is not always the case.
We have seen situations where everything appears to be running fine, but something feels just slightly off. Maybe it is a subtle vibration in a pump, or a pressure reading that is technically within range, but not quite where it usually sits. Those small inconsistencies are often early warning signs.
Tools like vibration meters, or even just paying closer attention to baseline readings, can make a big difference. Catching something early is always easier than reacting in the middle of the season.
The Stuff You Cannot Fix Later
Some of the most important checks are the ones that are hardest to revisit once the park is operational.
Things like ensuring grates and fasteners are secure before a pool is filled. Or taking the time to really look at slide seams and flumes early enough that, if something needs attention, you actually have time to address it.
Once the water is in, guests are in, and operations are running, it becomes much harder to go back and fix what you wish you had double checked.
When Close Enough Is Not Enough
There are a lot of areas in park prep where being slightly off does not seem like a big deal until it is.
Take tube PSI, for example. It is easy to assume that if a tube looks inflated, it is good to go. But small differences in pressure can change ride performance more than people expect. It can affect speed, rider experience, and even safety.
Some of these details may still seem small, but they can have serious implications. When overlooked or combined, minor issues can quickly turn into real safety concerns. Take chemical systems, for example. Probes that were not stored properly or settings that are slightly off may not raise immediate red flags, but they can lead to inconsistencies that create hazardous conditions if not addressed early.
The Unexpected Guests
Not all preseason surprises are mechanical.
Depending on your location, you might find that your park was not entirely empty over the offseason. Insects, small animals, even nesting bees can find their way into places you would not think to check. Inside equipment, under structures, tucked into corners that do not get much attention.
It is one of those things that is easy to overlook until it becomes a much bigger issue on opening week.
What Experience Teaches
For seasoned teams, a lot of this becomes instinct. You start to notice the small things without thinking about it. But that is exactly why it is important to talk about them.
New team members do not have that same context yet. And even experienced teams can fall into the trap of moving quickly past the little stuff because it feels routine.
Sharing knowledge, reinforcing best practices, and creating space for ongoing training, whether that is internal or through industry programs, helps make sure those details do not get missed.
Always Thinking One Season Ahead
One of the realities of this industry is that you are almost always preparing for what is next, even while you are opening for what is now.
The parks that run the smoothest are often the ones already documenting what could be better next time. Noticing what took longer than expected. What parts were harder to source. What small issues kept coming up.
Those insights, collected over time, are what turn experience into better and more efficient openings year after year.
At the end of the day, opening a park is not just about getting everything up and running. It is about making sure it is ready for the people who will experience it. And more often than not, it is the smallest details that shape that experience the most.
