They just about finished re-surfacing Kalakaua Ave. (main drag) in Waikiki so it'll be smoother driving on the strip before the US Post Office road as you enter Waikiki town.
Unfortunately, the cost of driving down the same stretch of road will cost you more. The gas station didn't even bother with posting the prices for Premium-gasoline and Plus-gasoline. Just last week the gas station had a separate space for Premium and Plus on the same sign. Premium and Plus are above $4.00/gal.
