I'd say plan to go on a hike to the summit for your first trip, but you can ask park rangers about the attractions when you are there. There is a service road which goes around the island, which you can hike, bike, or take a tramway to the various attractions, which mostly have been closed for decades and are in a state of ruin.
Id say, Do something crazy, like wear stripes with plaid. Otherwise @billmaines has the right (and more useful) idea.
Just put on your straight jacket and they'll scoop you on up.
You can rent golf carts to travel around the island
