Capri Italy Transportation

Here's a website detailing all the options. Don't worry about the very confusing charts at the top; scroll down to see descriptions of the steps: http://www.capri.net/en/getting-here.

In your other post you asked about a company to coordinate all the steps. If you want easy, there's a helicopter from Naples airport right to Capri (described in the link above). I have no idea of the cost, but given the multiple steps involved in other methods, I'd look into it.

Your hotel has directions for how to reach them once you've arrived in Capri:
