Vacation Rental In Kauai Hawaii

It is the first week of October a good time to go on vacation in Kauai (Hawaii)?
October is high season or low? Will many people? What will the weather be like? We intend to travel with young people 75 + years and one year more than 9 years, we are in our 30. We intend to get a package that includes airfare, hotel and rental car, some tips?
