This initially launched last week, but crashed the website due to demand. ccording to the BBC website, the offer will relaunch tomorrow (Saturday) http://news.bbc.co.uk/1/hi/england/kent/8552935.stm
Visit Kent, which organises the event, said the website would be relaunched on Saturday with a new application process to ensure tickets are allocated fairly.
It is offering 18,000 free tickets to more than 100 attractions on 27 March.
The application process will allow Kent residents to register for tickets via a ballot up until 1700 GMT on 8 March.
They will be asked to complete a sign-up form online with their five top choice destinations as well as an option for a lucky dip should the first five choices not be successful.
These requests will be entered into a ballot and ticket vouchers emailed to successful applicants ahead of the event.
Kent's Big Day Out 2010, led by Kent Tourism, is the fourth of five Big Days Out planned in the run-up to the Olympic Games in 2012
Venues range from sports centres and football clubs, to animal parks and country walks, with many museums and historical sites on the list as well.
