I'm excited for Hawaii

I bought a round ticket to Hawaii.
I wanna see a luau, take a zipline and go (in, to?) a shark cage. (in like inside the cage or to like to see the cage)
I can't wait to do these things. (technically correct but this is more idiomatic)
Could you recommend the best place to (go or see) in Hawaii? (in this case you need an action because one is not well implied)
I have almost 8 days there. (You have the days, not the time, in this case)
