Europe Honeymoon in October

Hello 🙂

My fiancé and I are getting married in a quick courthouse ceremony October 18th. We want to stay the night in Seattle that night (we live in western WA) and fly out the morning of October 19th to Europe. We will need to be back at work November 3rd, so plan on traveling back November 1st.

I am looking at Barcelona/Rome/Greece, but I really need suggestions on where we can enjoy warmish beaches and see some beautiful architecture. We’ve never travelled internationally and I’m trying to plan everything and it is proving to be very overwhelming. I likely won’t be in Europe again anytime soon, so I want to see as much as I can but also want some downtime to relax and enjoy the start of my marriage. Any advice is helpful and I’m open to anything! Thank you in advance! ❤️
