Justin's Water World was a mediocre water park. First of all, it's only open on weekends. That in itself is disappointing since there are days you want to take off from work to "play." After all, there are days when you don't want to stand in long lines... especially in a 100+ degree weather. Secondly, the slides and rides are like Justin's competition (Breaker's)... it's dilapidated. They look like they should be retired by now. The paint job doesn't look too attractive. This park is definitely for locals since tourists might expect more for their money. They would definitely expect some place nice to see on their vacation.
The Pros? You can pack your lunch and have a picnic in the ramada. Bring lots of drinking water. OR if you decide, you can order pizza. The food was good, and the service was great.
Bring sunblock and shoes/sandals! You'll need the sunblock for the blazing sun... and you'll need the shoes/sandals to prevent the rocks from baking your feet!
