According to Rollonfriday.com, trainees were booked into hotels overnight to ensure they could fully recover from the "Caribbean themed karaoke" events of the weekend. And to save money, the firm had arranged for trainees to share hotel rooms.

Unfortunately, due to an "administrative error" the travel company booked double beds rather than twin beds, and the mistake was discovered too late for alternative accommodation to be found.

To solve the problem, there were suggestions by the UK media that the firm filled its trainees with booze and let them go to bed together, taking trainee bonding sessions to a new level.

But a spokeswoman for the firm was adamant with Rollonfriday that there was a time and a place for shared beds, and that the trainee conference was not it: "Our trainee conference is an occasion for individuals to get to know each other, but booking our people into double rooms is definitely a step too far!"
