I'm a big fan of hostels. So cheap, plus you get to meet interesting people in the common areas. Do you happen to remember the name of the nice London hostel you stayed in?

Ah, good to hear that Stonehenge is worth it. Sometimes things that famous are not all they're cracked up to be (like the Mona Lisa, which is far less interesting than most of the rest of the Louvre).

*looks up Newgrange and Tara Hill* Ooh. That sounds really nifty!
