With great weather throughout the year, there’s no bad time to visit Hawaii. Hurricane season, from June to November, rarely touches the islands. Most domestic and international arrivals land in Honolulu. Hawaiian Airlines, Island Air, and Mokulele Airlines operate inter-island flights. The islands are large enough to make a car rental worthwhile. If you plan to stay in one place, taxis and shuttles are easy to arrange. Credit cards are not accepted everywhere, so travelers should carry some cash when shopping. A 15–20 percent tip is standard for restaurant bills, 15 percent for taxi fares, and $1–2 per bag handled at a hotel. Tips for tours start at $5 and increase based on tour length. Outlets are 110 volt.
