Bora bora or st lucia? Or somewhere cheaper with beaches.

Hey all, been reading all these posts over honeymoon planning and here's my situation.

Getting married in jan. 2026 but doing honeymoon in March 2026 (mid to late March) for 8 to 10 days. Trying to stay under 10k for overwatch but cheaper the better. Saw that costco travel had some deals but most of the cost doesn't show unless we are closer to the date.

Also got probably 100k in chase points to make it cheaper so what do you guys think? Very doable or save up some more? Thanks for info in advance
