Relaxing honeymoon in November 2025 for between 10-14 days – any ideas?

Would be flying from the UK. Budget would be up to around £8000 but have potential room for manouver there if we find somewhere extra special. We wouldn't want somewhere that has nothing to do at all and is just purely sitting besides a pool but also don't want an activity heavy holiday. We would like it to be somewhere warm but doesn't have to be boiling! Really struggling to find somewhere that fits this criteria at this time of year… Anyone have any ideas? Would really appreciate it! We did consider doing a cruise but most cruise liners seem to have very mixed reviews so we are not sure…
