I just used STA travel for the flights really. Heathrow to Bangkok then Singapore, Sydney, drove up to Cairns, flew to Christchurch, drove round South island of New Zealand the flew to Fiji LA and NYC. We turned up in Bangkok without any accomodation and got a hotel behind Koh Sahn road for £12 a night, 4 star too. It was easiest to just turn up places and worry about places to stay later. Also, we got a certain number of flight changes for free insted of £10.
