A good travel agent saves you time and worry by planning a trip around your budget and interests, handling bookings and helping if something goes wrong. Expect to talk about dates, destinations, who is travelling, what you want to see and what you want to spend, and to get a written itinerary with prices and terms. When choosing one, ask what fees they charge, what protection applies if a flight or hotel is cancelled, what insurance is recommended and who you call when you are overseas. Regulars know that booking early gives the best choice for school holidays, that passports need at least six months' validity for most countries and that travel insurance should be bought when you book, not later. Ask how changes and refunds work before you pay a deposit.
For anyone planning a trip from south Auckland, On Trip NZ on Port Way is a local agent to talk to.
