We have all heard the adage “hindsight is 20/20,” meaning, “it is easy to know the right thing to do after something has happened, but it’s hard to predict the future.” Whether as operators or guests, we have collectively survived the pools and parks of yesteryear, but do we know where aquatic trends are going? In this session, we will showcase and compare what we were designing 10, 20 and 30 years ago against some of our current designs and innovations. We will review technology and mechanical updates and upgrades that can be implemented into current facilities for back-of-house improvements along with accessibility and inclusivity advancements. We will discuss the aquatic amenities that have endured the test of time, those “golden principles” that we are constantly designing into new and renovated facilities. Attendees will leave this session with a grasp of where we have been and where the future will take us.
