It was a wonderful relaxing week in Kona for us. We stayed at the Sheraton. A great place! We had an ocean front room which I highly recommend. The Sheraton has a fantastic pool that meanders around allowing for more privacy than expected. Most families with children congregated in a couple of kid-friendly areas leaving the other areas quieter. Not that noise was a problem. They have a huge waterfall which drowns out most noises while adding a very pleasant sound. They have plenty of poolside chairs -- some resorts have too few. The food in the Kai restaurant is overpriced but it's a good place for breakfast. The Crystal Blue is a wonderful setting for a lounge. Their bar menu is reasonable - we had dinner there one night while watching the sunset. Our package included free mai tais each evening -- nice touch.
We also ate at a few restaurants that had been recommended on this forum. Huggo's, Huggo's On the Rocks, and Jamison's. All have nice views of the water. I wouldn't rave about the food at any of them but it didn't matter to us -- the setting was more important.
We drove to VNP in one day (against the advice given here). It was no problem. Maybe we missed a few things but we saw what we wanted to see and even stopped at Akatsuka Orchid grower to buy orchids for friends arriving back at the Sheraton in time for our mai tais! That day we had lunch at a small place in Volcano Village (I can't remember the name of it now).
One more thing --- after having asked this forum about the halfway to Hawaii contest on United Airlines (which I had never won in my 8 or 9 previous trips) I actually came in 3rd place this time! As no one on this forum had any surefire tips on how to win, I used my normal combination of math and guessing, so I still think it's mostly luck. But it's fun.
The weather in Kona was absolutely perfect the whole time we were there. Wam with very little humidity.
The only negative was the traffic. Just a minor issue really. I'm glad we were at the Sheraton -- away from the noise, traffic and crowds.
