Hilo, Honolulu, (Lahaina) Maui are some of the Islands which I have had the fortune to visit.  The active volcano is a sight to see in the dark sailing away from these gorgeous Islands.  The greetings you recieve off the locals is extra special too with lei’s in abundance.  You can even wear your Hawaiian shirt with pride and without feeling like ‘the odd one out’.  As for Waikiki beach, you can surf or just soak up the sun.  For the adventurous side there is even tandem skydiving.  So if you are thinking of going there or have been then let me know what you thought of it.
