I will be bringing my partner and father to Dublin next month for three days, before continuing on to other parts of Ireland. I have studied the Dublin Bus website and concluded that, based on the bus trips I think we will be taking, it is not in our favor to buy a multi-day ticket, nor does a Leap Card make economic sense, with the €5 supposedly-but-not-really-refundable deposit (at least for tourists), multiplied times three. So the best deal for us will be to pay fares in cash. Since the buses only accept exact change, I want to request the correct euro coins from a bank at the beginning of our trip. My question is, will drivers accept payment for all three of us at once? That is, if a fare is €2.35, can I pay €7.05 for the three of us in the form of three 2-euro coins, one 1-euro coin, and a 5-cent coin? Or I must I come up with three 2-euro coins, three 20-cent coins, three 10-cent coins, and three 5-cent coins as if each person were paying individually? Thanks in advance.
