Welcome to Boardworld, chloee!
Yeah, cords hit the nail on the head. It really depends on how disciplined you are. There's plenty opportunity to earn enough money, however it's also easy to spend in a resort town. Make sure you cook at home and don't spend all your money on pay-day drinks, as many workers do.
It definitely helps to work between the seasons. You don't need a great job, just a somewhat steady income. It makes it so much easier if you can pay for your flights and have money left over. You also want to be able to enjoy your time over there, so if you can save up prior to travelling, why not?
Where are you thinking of going?
