Destination Wedding -small Ceremony Large Party Later

My fiancé and I are planning a wedding in Greece. Specifically it’ll be a small ceremony (parents and siblings and their plus ones) and a dinner. We want to keep it simple because if we try to expand the list to aunts and uncles and cousins and their spouses it’ll easily get to 50 plus people, raising the cost on top of figuring out travel logistics, etc. To make up for a small ceremony we plan to have a large “celebration of marriage” party a few months later with all friends and family invited. My question is - would this set up be offensive to anyone? Any insight would be appreciated. Thank you.
