Thanks everyone! I didn't know about the two airports...very helpful. I believe we will stay on the north side of Kauai...that's the sunnier side, right? I thinkwe are going to get a Kuhio Shores condo for Kauai, and stay in a B&B on Big Island (probably Waterfalls Inn, if we cna get it...we have plenty of time to book).
We are most interested in outdoorsy things, like snorkeling, hiking, seeing the volcano, waterfalls and rain forest, and probably beach for two days. We don't play golf, but my boyfriend will probably want to surf someplace. He's a beginner, so nothing too crazy, (he's only surfed once before in California). I'm most interested in seeing birds/animals/plants...that sort of thing.
I think we have 12 days. We will stay one night just outside of the airport, since we will arrive late. Then we will fly to big island, stay for 5 nights, and then 5 nights in Kauai, I think.
Any advice on what to do would be great! I read somewhere that the snorkeling is really good in Kauai, right where we plan at Kuhio Shores.
