We will be having an 18 hour trip, finallly landing in Christchurch around 5pm. We plan to spend the night at a hotel near to the airport, which offers a free shuttle back to the airport the next morning. We will then rent a car. My question is that a lot of the cheaper car rentals seem to say they offer a shuttle bus to their rental location, so would I be then taking a shuttle from hotel to airport and then another shuttle to somewhere else and how much hassle would this be with all oru luggage? Would it worth paying more and just renting from a company that has a location right at the international terminal?
