Parents Not in Agreement with Elopement

My fiancee and I (31 and 33 yrs old) have been dating for 12 years. He proposed last year while we were vacationing in Ireland, and we fell in love with the country so much that we are planning to elope there in September! My fiancee and I invited our parents to be there with us and that’s it no friends, other family members, etc. When I told my parents they were upset and said they were “devastated” with this plan. Ever since they have been trying to guilt me into doing something else here at home just for the family. I don’t even have a close relationship with my extended family at all, and my fiancee doesn’t have anyone on his side of the family except for his parents. I have never been interested in having any type of big celebration, traditional wedding, etc. and eloping just always made sense for our relationship! We love traveling and adventure, so eloping in another country just feels right for us! How have others dealt with their parents not being in agreement with their elopement plans? I know everyone says “do what’s best for you”, but that’s much easier said than done!
