Aqua imagica and imagica are besides each other but are different amusement parks. I have visited aqua imagica on 10 feb 2016 with my classmates. Here is my experience.
The rides are awesome. You need to visit every ride. The experience is unforgetable.There is a slide that is 90° down right from a height of 4th floor. Its scary but a one time visit.
There are other rides too mostly the 4 tube one in which four sit in one tube and goes into the slide. This one too is unforgetible. River rafting should be done in group as alone wont be much fun.
Each and every ride is atleast a one time visit if you are visiting aqua imagica.If you are visiting in a month from now, just postpone the date as the wave pool is under maintenance currently and will be for the ongoing month.
