We are planning our first trip to Maui and would really like to stay at Napili Kai. We are coming from the Midwest so March is our first choice since the weather here is usually still chilly and wet and we would also love to do some whale watching. However, if we are much better off weather wise to go in April our schedules are flexible. We are interested in snorkeling, etc which is a bit why I am concerned about the weather. If it makes a difference we would either go the last week in March or the last week in April. Thanks for any insight!
