有冇人去過夏威夷玩?

For Hawaii hotel, go to www.Orbitz.com, one of the biggest travel site in US.
very reliable.

Hawaii technically does not have sales tax, but it has an excise tax in general retail at 4.5% and wholesale at 0.5%. So th receipt may have no sales tax on it but the merchant usually includes the taxes (4.5 and 0.5) in the final price.

Things in Hawaii are generally very expensive.
