Travel and Accomodation

---

The meeting will take place in Room E1 of the Department of Physics and Astronomy. This is on the ground floor of the Department. To get to UCL have a look at http://www-server.bcc.ac.uk/UCL-Info/AboutUCL/Transport.html . We are handy for Luton and Heathrow Airports, and Euston and Kings Cross are very close to us. To find the Department take a look at

We are off Gower Place at the top of this map.

Accommodation can be booked via Christine Johnston (christine.johnston@ucl.ac.uk) at UCL. Please give her a price range for your accomodation and she will book you into one of the local hotels.

Wireless and Network Connections
