We've searched around the web for the best rates we can find, after all Frankfurt 09 had a shockingly low exchange. This years is not great by any stretch of the imagination but with a little work you can make the most of what you have to spend.
We found a few minutes spent on travelmoneymax.com gave us a list of options and rates. Seems obvious to say this but if you go along and do the exchange yourself you will be offered a better rate than having it delivered.
The search interface is simple to use and the results are displayed in order of best rate. We think this site is a money and time saver but if you don't agree feel free to post a comment below.
