RyanAir is an Irish low-cost carrier. It's main bases are Dublin Airport and London Stansted.
It costs about $181 to hire an economy Volkswagen car in Dublin for a week. It may cost more or less depending on the brand of the car and how long you intend to hire it.
The cost of an apartment in Dublin, Ireland will vary greatly depending on many factors, some of which are the location of the apartment and the size of the apartment.
That would cost a massive amount as it is about 90 miles. A lot of taxi drivers would not drive that far. You would get a bus from the airport to Wexford or a train from Dublin city centre for a fraction of the amount you would pay for a taxi. Dublin Airport is about 8 miles from the city centre, and a taxi fare for that could be about €20. You would get all the way to Wexford by bus or train for only a small amount more than that, maybe €23 to €25. So it would be crazy to get a taxi. To go by train, you would first have to go to Dublin but there are buses from the airport that would get you there for far less than a taxi. You could get a bus from the city centre to Wexford from Busaras or a train from Connolly Station, both of which are just a few minutes walk from each other. There are buses that go direct from Dublin Airport to Wexford, but they would only go every 2 hours or so, so depending on your arrival time, it might be better to go to the city centre and travel to Wexford from there. Check the Bus Éireann, Irish Rail and Wexford Bus websites for more details.
A one-way ticket from Cork to Dublin is 33 euros if you buy it online.
There is a fairly wide selection of places to park in Dublin if one is using the airport. A search carried out for a week's parking brings back results of approximately 35 Euros. Parking can probably be found significantly cheaper than this if one has a discount code or books further in advance.
