Euro currency exchange

[001_ATLANTIS]

I came back with a fair amount of unused euros last summer with the intention of keeping them for somewhere in Europe in 2020. However the holiday gods are shining on me and we are now going back to Florida instead. Yippee!

I'm trying to work out the best way to maximise the value of what I have. Should I convert from euros to sterling here in the UK first and then change the sterling to US dollars before travelling or am I likely to get a better return by taking my euros to the US and converting them there to dollars in one go?

I just thought that it might be more advantageous to convert once as each time you loose out but I'm unsure what conversion rates and commission charges are likely to be like in Florida. It would be great if someone has had experience of this and can make some recommendations.
