Advice....

Personally I don’t see an issue with it. I am eloping because neither one of us wants to spend an extravagant amount of money on a wedding. We feel celebrating our love with an intimate ceremony including family and a few close friends is more important. We feel there are other big purchases that require our money like the custom home we just built. So go for it!

I don't foresee an issue with it. That all sounds good

You need to host your ceremony guests in some way before leaving to go on your honeymoon.

Hi there Qieron!

This sounds like a wonderful idea. Lots of couples elope and then have a vow renewal and celebration sometime after

As Vicky mentioned, it would be a nice idea to host something for guests who attend city hall to thank them for coming. It can be as simple as lunch or food back at your own home. Were you planning on doing something already that you haven't mentioned?

There is no need to host anything after a simple city hall wedding. If after to depart for the cruise, others want to go out together for a snack, they may. But if you are going to the cruise docks, hosting something is not at all necessary. And delays everyone. Recently people always say you need to host something, or give a gift, any time you do anything. A group goes dress shopping, some will post, you need to host something after. A wedding rehearsal they may be 1/2 hour on a weeknight, locally, with a full RD dinner a week or two before of after, people post that you need to host something that very night. But like presents to people you are going to ask to be in your wedding, presents to those who get ready with you, complimentary spa days, presents for your parents before the wedding, presents for FIL before the wedding, and a huge number of things suggested on WW: you can do what you want. But there is nothing required by etiquette, or established custom, that you need to do any of it. There is a much promoted push to give presents or treat someone to a meal, which benefits the gift and hospitality businesses profits. But giving out presents, or feeling no one does anything without then getting a meal, is a not social convention. And not necessary. It drains the budget and can be burdensome when you have time constraints . People who generally care for you can and will happily come to your special occasions, without getting a treat for their behavior. Get married and bon voyage. And let everyone know you plan to hold a reception on a later date. That is fine. I have never heard anyone complain, unless the original marriage ceremony was kept secret and people felt deceived that you had a charade of a wedding after, and not an honest party or reception for an already married couple who simply want to share their newlywed happiness. . . . In fact, given the huge numbers of family and friends of couples who really object to destination weddings, where they cannot see you marry unless they take a vacation and spend a lot they do not want traveling, a whole lot of people love it when they can see a couple marry, then send them off to do their honeymoon trip with those who want to travel, delaying a party til convenient for everyone. Which is actually the more traditional thing many prefer to destination weddings. There is no mandatory hosting those at a civil ceremony, before going to the cruise . Delayed gratification, party later, is fine .

I think that sounds awesome! Just be sure to leave time to get everything done, to me it sound a little stressful to do all at once, I might try to do city hall the day before, have a nice dinner with family and be ready for the cruise the next day, but it sounds like you have it all planned out to work fine!
Just make sure you call the reception next year a vow renewal, a lot of people a weird about that, but it can be exactly like a normal wedding otherwise! You just aren't saying i do's, you're renewing vows (in an awesome wedding dress)
