You're considering only the Euro; for most other currencies in the world, the dollar has weakened lately.
Most of the time between 2000 and 2011, the AUD was in the 0.70-0.80 USD range, with the odd drop to 0.50.
The AUD recently reached 1.07USD and is currently ~1.04.
I do holiday in the USA every year- twice this year but short breaks not main holiday.
The
only reason I visit the US for any length of time is because my friends are there and dealing with the crap DHS thinks of is the only chance I have to see them offline.
