December honeymoon- ideas needed

Hi, I’d love advice in narrowing down some honeymoon options. We are looking for: • travel between 18-31 December 2023 • 10 or 14 days total ideally • budget of £6-6.5k for flights and accommodation • somewhere warm where we can lie by a beach/pool and not move (if we don’t want to!) • happy for all inclusive or not but don’t want to be reliant on driving for food • flights from UK- not too bothered on length of flight

Any ideas? Thanks in advance!
