We are visiting Big Island for first time in either May or September, staying a week in a condo, 2 senior couples. We are open for suggestions as to which area is better, Kona or Kohala Coast, and is there an airport on the W side of the island? We want to see cultural areas, some beach going, and lots of chill time with a few dinners out, but mainly cooking in at night. Also, are there any flights direct to Big Island from either LAX or San Diego, or even Vegas? Or do we need to fly into Oahu and then on to BI? We are planning on a week on BI and then another week on Kauii, either Kapaa or Poipu Beach area. Could I have some suggestions as to which is more convenient to do first? Thank you.
