Beautiful (easy on the wallet) honeymoon destination advice

Hi! We got married 2+ years ago, with intentions of doing our honeymoon in 2020. Covid ruined our plans, so we kept postponing. We wanted to do Thailand, but with travel restrictions, we decided not to. But we don’t know where else to go. We thought Hawaii or Europe (Caribbean is NOT an option for us, since we’re from PR and we’ve seen a lot of the Caribbean throughout our lives). Budget is around $5k-6k USD. Can you recommend me a destination?

Edit: we’re planning on traveling Sept or Oct 2022
