October (warm, fun, relaxing)

Looking for potential destinations for a 2026 honeymoon in October! We have 8 days so have to be mindful of intense travel. We want something that is warmer beachy weather, but that allows us to also explore around. Somewhere you wouldn't ordinarily go and a more luxury type of experience. Any island or hotel recs??? Totally fine saving money on a flight to somewhere in the Caribbean and then using more towards a fancy place. Once in a lifetime thing! Thanks!!
