We are a family of four with 2 daughters, ages 10 and 20. We are planning a trip to Hawaii for 3 weeks. My cuurent thoughts are some time on Oahu and Kauai. Maybe some time on Maui, but it does seem flights between islands are a bit pricey. I am thinking to rent a condo for some time, stay in anice kid freindly resort for some time and maybe some budget hotel time as well. I am looking for any advice as I am just starting the planning of this trip that we will be taking in July.
