Early in organising this trip I was eager to visit CERN. I knew they had guided tours of the facility, and they were free, you just needed to book them. Each day at about 4:30PM AEDT / 08:30AM CET they open up spots on the tours to book 2 weeks in advance. At the sametime they also open up spots for tours for that same day if they have any spots free.
Within minutes all the tours are booked out.
I set a reminder on my phone, and took my laptop to work – not trusting the incredibly expensive corporate internet connection, instead relying on my phone’s 4G. As with most work days I got distracted by something around 4:28PM and by the time I had refreshed the CERN website to see what tours were available all the spots were taken.
Despite this I was determined, and logged in most days to keep an eye on the numbers.
