Shameless plea for summer vacation help

<p>So this is my shameless attempt to get some help on my summer plans. My dad and I are vacationing in South Hampton and Montauk this summer and we want to go up to some of the islands around there: </p>

<p>1) Is it possible to take a ferry(s) to Nantucket from Montauk? If so, where? (I’ve looked everywhere and can’t find a system to get to Nantucket) </p>

<p>2) I know that Block Island is easily accessible from Montauk. Is Block Island worth seeing if we can’t visit Nantucket? </p>

<p>Any advice from ‘seasoned’ vacationers/people who live in the area would be awesome. </p>

<p>Thanks!!</p>
