I have not been to the water theme park if it is located at the town of Ipoh, I would pick Casuarina or Heritage (business hotel).
Come to think of it, Ipoh is a very small city so am pretty sure you gonna drive around so shouldnt be a problem to get around I think..
Besides water theme park:

Be patient toward all that is unsolved in your heart. Do not now seek the answers, which cannot be given you because you would not be able to live the questions now... Perhaps you will then gradually, without noticing it, live... into the answer ~Rainer Maria Rilke~
