Hotel Information
Here we provide a non-exhaustive list of hotels in the West End and City Centre of Glasgow. The price brackets given are approximate, so please browse around the various hotel booking sites to find the best deals.
West End (Great Western Road)
A selection of hotels along, or near, Great Western Road and all within roughly 20 minutes walking distance of the meeting venue. Note that many of these hotels are quite small with only a few rooms available.text/html2017-12-06T17:51:14+01:00igr-public:borja_tedxmadrid-media

Hi all,
Fiona and I are delighted to announce the arrival of our beautiful son,
Corran Scott P-L. Born on Friday morning at 11.38, 7lbs 1oz. We were
fortunate enough to catch some of the eclipse before all the real drama
began!
Fiona and Corran are both doing really well so we got home yesterday
evening. This is where the fun really starts!text/html2018-10-09T20:13:24+01:00igr-public:start
