Council bosses have come under attack amid fears landmark attractions in a seaside town will close unless millions of pounds can be found.
Multi-million-pound investment is needed to bring some of Eastbourne's best-known attractions up to standard.
These include the resort's four council-run theatres and its Grade II-listed bandstand.
But the Eastbourne Green Party has accused successive Tory and Lib Dem administrations at the town hall of starving the venues of investment.
Principal spokesman Clive Gross said: "The non-investment in our major tourist attractions and theatres by successive council administrations has brought us to this point.
"Both parties have overseen their decline to this state. Action could have been taken to avoid this situation many times over many years."
Finance officers at Tory-run Eastbourne Borough Council have admitted "difficult choices" are needed to solve the "daunting" financial plight.
Public consultation costing £20,000 will find out what attractions voters think should be saved. But yesterday the Greens said it appeared decisions had already been made.
Mr Gross said: "In reality, Eastbourne residents will once again be left with no real democratic say in the future of key aspects of our town and to who these public assets are eventually sold or leased."
Earlier this year, the Greens accused the council of neglecting Eastbourne's other tourist events by concentrating on its four-day Airbourne airshow.
A row erupted over claims by the council that Airbourne was worth £20 million to Eastbourne's economy. The Greens said the figure was invented to create better headlines.
Party members now say that if the figures are true, a slice of the £20 million could save some of the threatened attractions.
Constituency co-ordinator Leslie Dalton said: "If the figures banded about as to the value of Airbourne to our town were accepted as true, just a ten per cent cultural levy on the proceeds from the event would sort out our Bandstand.
The council has said the solutions "require difficult choices" but said its prime aim was to seek a sustainable future for the service provided to the public.
