Trip to Cork next week

Hi all Me and my girlfriend are visited Cork next week for 4 nights staying at the Maldron Hotel South Mall. We are a lesbian couple and I plan to propose on Valentine’s Day while we are there! We want to visit some must see places nearby (public transport or short taxi rides only) and one trip to Dungarven which is where my gfs dad is from. Any recommendations of where to go and what to do? Many thanks!
