One-way car hire: Belfast, Dublin or Scotland?

What most people said

• For Belfast to Dublin one-way, most point to big firms like Enterprise, Europcar or Sixt; expect a cross-border fee and a drop fee.
• Some smaller firms (My Irish Cousin, New Way) won't do Northern Ireland drop-offs, so check first.
• Taking a hire car from Belfast to Scotland is widely discouraged: costly ferry, often not allowed. Most say fly or coach over and hire there.
• For a short Dublin stay, many say return the car at the airport and take a bus or taxi into the city.

What people said

• We do this all of the time. You're going to pay a cross border fee and a drop fee. Use a bigger company like Enterprise.
• Rethink your plans! Return the NI car, fly over and get another car for Scotland.
• The airport is near the city and also on the M1 motorway that takes you to Dundalk. I would return it to the airport and take a bus or taxi into Dublin.
