I asked this same question the other day regarding August and the hands-down winner was Kapalua. But am toying with a trip during whale season (next mid-Feb.) and want to know what location would be best in terms of weather/beach conditions, etc. We will definitely pick a villa or condo style resort. We have 2 kids (11 and 8). We like to snorkel, explore the island, and lounge on the beach a bit too.
