1. Take Advantage of Public Transport
2. Know How Your Money WorksThere are lots of money facilities available to travellers - in addition to the usual cash currency conversions and VISA/ATM withdrawls - there are VISA debit cards and travel VISA/Mastercard cards which makes it all easy to thrash the finances! There are other interesting mechanisms that caught me off-guard when using my AirNZ OneSmart Mastercard: The OneSmart card has individual 'wallets' - each one representing a different currency and you can transfer between them easily. The default one is NZD. So I had some funds loaded in AUD - meaning any purchase in Australia will use these already-converted funds. What happened in some places, was unexpected - particularly at ANZ eftpos machines - it prompted me to select their preferred currency rate. Somewhere in the OneSmart information, it does mention some banks bypass the systems in place. Something to be aware of.
3. Full Price is for Chumps - Check Your Loyalties
The other big deal when it comes to taking advantage of savings is your loyalty cards. Kathmandu Summit Club? Works over there. Happen to work at a Progressive-owned store (DSE, Countdown, etc.)? Works in Australia too (and even gives fuel discounts!) along with many more reward cards. So, do a little bit of homework and see whether it will work overseas - chances are if they have the same scheme it will mean a few more dollars to spend large with.
Never, ever, pay full entry cost to a theme park - chances are your accommodation, travel agent, Entertainment Book card or big corporate cards will give you access to tickets at a severely reduced price. While we were overseas we also found the theme parks offering half-price tickets online for certain off-season months!
