I was looking at your same options and we finally decided on both. We were considering 2 hotels anyway (3 with vnp) and i think the Hapuan and the Hilton will give us the best of both worlds so to speak. We are going for 2 weeks with a 7 year old so we will do 6 nights at Hapuna, one night at VNP, and then spend the last week at the Hilton. From all the great help on this board it seems like a good plan for us.
