True it doesnt have many rides, we reached there at 3pm, yet we were able to enjoy a lot. The only cribbing is that we have to personally carry the tubes all the way up for water slides. There are two slides where you can directly slide without a rubber tube.
They close at 530pm, which is a little early in my opinion.
The life guards are visible everywhere and quite alert but not the most knowledgeable.
There wasn't much rush on the weekday evening.
Frequent buses are available but the nearest stop is 500mts away - it did seem more like 1 km. There is Pilikula zoo nearby which can be covered in less than couple of hours.
