I have $1000 that I didnt use on a recent holiday.
I'm not sure what to do with them! Would I be better changing back to pounds, or change to Euros (which I could use next year for a planned trip)?
I've googled and googled trying to find out what I would get back in pounds/euros but I'm getting nowhere as all I can find is changing £s to $\€s
Anyone a lot bit more knowledgeable than me, that can give me some advice 
Thanks
