Roller-discos were a hugely popular trend in the 70s, at a time when disco meant 'disco'. In this ridiculous era of health-and-safety gone mad, the harmless roller-skates have been replaced by roller-blades (yeah, they're not dangerous are they) and silly silver scooters that always look like they might disintegrate upon contact with a wayward piece of gravel.

Roller-skates rocked - the good news is, they haven't completely died-out because the O2 has been running a Kiss 100 Roller Disco since the spring and, whaddya know, it's been rather popular. This being 2010 sees the concept updated with today's latest hits (as well as some classic disco smashes) and a separate over-16s period for Fridays - Sundays. To this extent, the venue has opted to extend the season until 5th September and tickets are now being snapped up for the Bank Holiday at an alarming rate, it seems.

Standard admission is £8 for daytime tickets (Monday to Friday) - admission to the rink at the venue's Piazza starts at midday (10AM Saturday and Sunday) and finishes at 8pm, with the sessions lasting 2 hours. From Friday - Sunday you can opt for either a daytime or evening slot (8PM - 11PM, costing £10.50), which is restricted to over 16s.

Note that for daytime sessions, all children 12yrs and under MUST be accompanied by an adult. It's a relatively cheap way of keeping the family entertained for a day, especially if the weather's dodgy outside - family tickets cost £7 per person (for multiples of 4) for daytime tickets - all prices plus fees.
