I'm headed to Europe for work for almost the entire month of June. I'm leaving June 2nd. Spending the weekend in London. Working a few days in Oxford. Heading over to Paris to meet with some colleagues. Flying to Basel to talk to some IT folks. Back to London for a web design conference. Flying from there to Barcelona for a tech meeting. Then up to Madrid to meet with a customer with my former counterpart. It's an insane schedule, and I don't know how I'm going to pack for it, but it should be incredibly productive and, well, fun. Just for good measure, I'll take a week of vacation at the end. Somehow I need to get from Madrid to Amsterdam. I think I'll manage.
(The biggest mystery of the whole trip is just how many of the precious things that I leave behind in my place that my cats will piss on in my absence).
Wow! Somewhat jealous. But then not really, as I've been to most of the places on your list...well, except Madrid. HOpefully someday soon.
Either way, I think you have to pack with a couple temperatures in mind. Spring is trying to break through in London. But I suspect summer weather has already reached Barcelona/Madrid.
Jack here from Aus,
I am now in London, we should try to catch up while you are here. Drop me an email I assume you can get at it from here.
