If you are using a GPS, most seem to like the address format as 14 MA-6A Sandwich, MA.  If Sandwich Inn and Suites does not come up, try searching for the Shady Nook Inn, which is what the place was called before this summer.  Or, try searching for Twin Acres Ice-Cream, which is across the street from the inn.  When coming into the cape on either bridge, stay straight on 6A and the inn is the very first property after the Entering Historic Sandwich Sign in the Kiwanis Park at the split with 130 to historic Sandwich and Tupper Road toward the Canal.  Coming down Rt 3 over the Sagamore Bridge, take exit 1C, go past Market Basket to Sandwich Road, then turn right and we are about a mile on the right.  If coming over the Bourne Bridge, take the fourth exit towards Hyannis on Sandwich Rd travelling along the lower side of the canal.
