International or Domestic Honeymoon?

My fiancé and I are deciding on honeymoon destinations. We have it narrowed down to 2 options. The Biltmore Mansion Estate in North Carolina or somewhere in Dublin, Ireland. We would be staying for a little over a week. What are the pros and cons of an international honeymoon? Too exhausting with time change? Did you feel like you didn't have enough time in the country? We are both from the states.
