Flights around Summer cost £350-700, the earlier the better. Don't go during school holidays time, big mistake!
Training was around $130 but that might have changed. I'm pretty sure it went up to $170 if you dont sign a long-term contract. The accommodation for me first time round was $25 a night in a hostel, but that one is awful. Orbit Hostel, sucks!
Food is similar to England, you can get by on cheap Ramen Noodles!
Not sure if I can make it this summer, but I'll definitely be trying!
