Aloha! Congrats on winning a trip to paradise!!If you will be on Oahu, I suggest making sure your hotel room as a fridge and microwave, you will save a ton by stocking up on snacks, breakfast foods and maybe doing a picnic lunch a few days.Also suggest you try plate lunch, its a local favorite and there are tons of great plate lunch places. Plate lunch is usually a scoop of rice, macaroni salad, slaw and 1-3 meat entrees (pork, kalbi beef, mahi mahi, chicken) lots of choices, and all for $7 or less!There are lots of local magazines full of coupons, 2-1 dining, or activities, so do grab them whenever you see them. There are also lots of free and/or inexpensive activities on Oahu, Hawaii does not have to be expensive!Wakiki beach + lots of activities there - freePearl Harbor - freeTour China Town - freeHike Diamond Head - $5Snorkel Hanauma Bay - $5 (amazing)Enjoy surf culture on the North shore - freelots of museums, galleries etc - cheap or freeDrive up Tantalus Mt - freeWaikiki Aquarium $7and so much more!!
