You get to see 360 degree view and then a really nice meal at the top,($21).
Friday- In the morning around 10:00 plan to visit the Orana Wildlife Center, they are one of the most open wildlife centers in the world because there are few fences and you are allowed to feed some of the more tame and less dangerous animals,($28). When your done there around noon you might want to see the Cardboard Cathedral, a church made of all cardboard. Later eat at May's Thai, a place that most people recommend,($20-$30)
