Planning evening and one day at/around Niagara Falls
 

We are visiting Niagara Falls for short time and trying to make good use of that time. We will be driving from Kingston on Saturday, will reach Niagara Falls area around 5 PM. Here is rough plan, I can think of, after reading some blogs and posts -
Day-1 : Spend time in/around Clifton Hill. In later night, drive to see Falls illumination.
Day-2 : Drive and park near Fall. Do Hornblower Niagara City Cruise and visit Journey Behind the Falls. Drive to another parking area and do White Water Walk. Where should I park at both places? or I should park at three places (cruise, Journey behind the Falls and White Water Walk) ?
Day-3 : Niagara Parks Power Station and Bird Kingdom or Butterfly Conservatory in morning and leave by 2 PM.
Would you guys suggest some other way, or add/remove something from it?
Thanks in advance
