Late October European Trip

Hi friends!! I’ve seen a lot of tropical options for Honeymooning but my fiancé and I would like to do something different because I’ve never been to Europe. Our wedding date is 10/25/25 so we would probably leave a couple of days after. We have looked into Ireland, Italy, Germany, anywhere in Scandinavia, etc. We are considering a river cruise where we can hit multiple places, but would love to hear if anyone has personal experiences with inclusive options. We don’t have a specific budget in mind. Thanks in advance!! <3
