The Tidewater Inn in Easton is back in business. The new owners closed on it a week ago, and it already has hosted several weddings and several other functions. John Wilson heads the investment group that paid just over $4-million for the long-time hotel. Wilson also owns the Chesapeake Bay Beach Club on Kent Island, which does a lot of business with weddings and other events. Wilson says he will market the Tidewater Inn in much the same way.
