I was think about this last weekend actually, you would think the bigger competition for the Rapids would be all these local municipalities opening up their own waterpark and stealing away a lot of the local families. For instance, City of Palm Beach Gardens where I live has an aquatic center with an Olympic size lap pool, another olympic size general pool with 3 smaller size slides, rock wall and diving board, a smaller size kids splash castle thing and then a splash pad with fountains, and for residents cost us $3.00 to get in so seriously for a full day of fun is beyond worth the money. Compare that to the Rapids at $47 on the weekends then $20 to park its nowhere near as affordable for families. Sure these local parks don't have the big slides and everything but its something I know us as a family could do often over the summer.
I would imagine it will lose some business with places like the Broward County schools and camps that drive up here.
