Campaigners fighting to save the Dreamland theme park in Margate are giving evidence at a public inquiry.
Campaigners say the theme park is vital to the town
The attraction closed in November 2003 but has been given a temporary reprieve for three months this summer.
Protesters say they want Thanet council to change the local plan to allow the site to remain as an amusement park instead of being redeveloped.
The council said the planning inspector would look at using the site as an amusement park and for other activity.
Chief executive Richard Samuel said: "The Dreamland site has never been completely covered in amusement park activity.
"There have always been other activities around the edge of the park, so a mixed situation could be made to work.
The council says the site is being considered for mixed use
"That is what the planning inspector will be looking at - what the best way is to build a policy to protect the use there for the benefit of local people."
Susan Marsh, who is representing the campaigners at the inquiry, said: "We are working with several established amusement park operators who would like to acquire the site and invest millions of pounds in new rides and attractions.
"But all offers to acquire the site have so far been refused.
"It is our opinion that the offers have been refused as a result of the local plan policy being changed."
Some of the old Dreamland rides have already been removed, but the Scenic Railway - the UK's only listed rollercoaster and the oldest in Britain - is still at the site.
