My son is planning a NYC wedding in June 2015. We will be travelling from Scotland for the wedding and want to add a relaxing beach holiday after the wedding, probably for a week or so. We don't want to travel too far and are thinking of somewhere in the Hamptons, accessible by public transport. We may hire a car for exploring the Hamptons but don't want to drive from NYC. We like good restaurants and a little bit of buzz but not too busy. Any suggestions very welcome, thanks.
