Marray_NN,
I think if you weigh up the difference between the air fares, i.e. £500 then it would be wiser to go to Florida.
That is unless you can get discounted travel, even so - its 10% of the FULL economy fare so you'll still be saving.
I have been looking around and flights to Florida are around the £200 mark, compare that to a flight to Sydney about £700. Thats another 10hrs of flying in the difference of air fare.. .There are some good schools in Florida just need to search for them.
Hope this helps.
