If you only stay one, get in hotel by taxi at night since you are not familiar with the place,but on foot it takes 11 minutes from 三津浜 to hotel n go to Matsuhama station by railway very easy.
If you stay more than one night, the choice is very limited, only three place to enjoy the dinner such as economy restaurant and 燒肉鋪 to 23:00, on foot to there only three minutes.
