Oct 2025 Recommendations (relaxing but fun)

Me and my husband are looking to plan our honeymoon/1 year anniversary. I'd love an all inclusive option, adults only, with good food and things to do. We're flying from Atlanta so prefer travel less than 5 hrs (travel time is the reason im not looking into maldives, greece, etc😭 but one day). Looking at 4-5 days. We would really like a beachy/relaxing atmosphere but also with the option to experience at least 1 excursion/activity. Live music/nightlife would be fine for a night but this is not a must. Looking for any recommendations. Overall Budget is $5k but flexible if its worth it. Ive been looking at Travelzoo but wondering what other options are out there for affordability. Thanks!
