Group Honeymoon Invitations

My fiance and I have been together more than 10 years and have been traveling with friends and family for most of them. We are having a small (40ish person) wedding near our home in Florida. We plan to honeymoon in Jamaica. We would like to invite anyone that wants to join us on the honeymoon. Many of our guests are coming from out of town, so the wedding would be a stopover on the way to a great Jamaican vacation. I think we should let everyone know when we send out save-the-dates so they can decide and plan for Jamaica. Has anyone seen an invitation like this, and how was it worded? Everyone needs to know that Jamaica is a separate cost from the wedding, without pressuring anyone or making them feel like they have to come. Please help me find a way to invite people that want to come with fewer words than it took me to explain it lol
