Fiji vs. Vanuatt

Hi!

Been working in Australia for a year but leaving soon so want to go on holiday in South Pacific for 4/5 days. Based on budget, I've narrowed my choices down to Fiji or Vanuatu, but cant make up my mind.
Looking for a relaxing but fun-filled holiday - snorkelling, living in bungalow on beach (closer to water the better), shopping, massges, 4x4 tours, hiking to interesting spots, and beautiful scenery.
For those who have been to both, how do they compare? If you could choose to go back to either Fiji or Vanuatu, which would oyu choose and why?

Thanks,

Lameez

Been to both and prefer Vanuatu, but Fiji probably matches your expectations better, especially considering your time limit.
