hawaii holidays 2009

Hawaii Planning Questions!! HELP?
Planning a holiday in my first year off school before heading onto University in 2010. I am planning a week/+ holiday in Hawaii. I have found cheap fares which are $735 return with Jetstar, and this deal is nearly Half Price! I am thinking of booking around Aug/Sep/Oct 2009. Which is considered the “Cheap Season” as in Dates?? Some people just say “September is cheap” but is this half way through, toward the end???
Also, I am looking at staying in the main part, Waikiiki. Is it cheap if I book early, like booking hotels in around Jan-09?? Im only a student going by myself, so I only need 1 bedroom. But I want to be close to the central area, not miles out of town. In AUD, what am i looking at per night, in at least 3stars hotel, $100 or $150???
Finally, is Hawaii Safe?
Check with Pleasant Hawaiian Holidays, they have all kinds of different fares and costs for hotels. and yes you can stay right in Waikiki. Easy
they will probably beat the jet-star rate with a hotel thrown in. good luck
