Off to Europe next week

[ozimax]

OK folks, here we go again, overseas trip #55, (being work and a fair bit of sightseeing thrown in). If anyone would like to contribute some sage advice/hints/tips on what to do/see/explore/photograph in these areas, fire away. (I have been to most of these places before, but others know more about certain places than I do, so suggestions are always welcomed). We will be based in the following locations:

Rome (6 days)
Madrid/Valladolid (2 days)
Northern Ireland (6 days)
London (6 days)
Zurich (3 days)

Any advice will be appreciated. I will be taking only an Olympus E-PL2 + twin lens kit, for the sake of travelling lightly.

Many thanks,

Oz.
