Vava'u accommodation

Hi we are going to Tonga at the start of June this year and are looking for accommodation around $100-150 NZ per night. Any suggestions? we like the look of the Bayview Tonga and Island Explorer accommodation but note there are no threads about these two places. Has anyone stayed there before and can offer some advice. Also how does it compare to somewhere like Lucky's which also looks very nice.

Thanks,

Simon and Belinda
