@erikaaltman! It totally depends on what fun, outdoor activities you want to try! There are expensive and inexpensive hotels too! Luxury hotels provide beachfront rooms, bars; and I totally wanted to experience that!!
@stephwood, The six main islands west to east, Kauai, Oahu, Molokai, Lanai, Maui, and the Big Island of Hawaii, if anyone wants to explore minimum, still need 3 weeks. As Honolulu is closer to the airport, it has become most popular among others.
