A campaign group seeking to preserve a green space on Skegness seafront has vowed to continue its battle to prevent development of the site.
The landowner East Lindsey District Council launched a marketing exercise to consider bids from potential purchasers in March.
On Tuesday, the authority’s Executive Board recommended acceptance of an offer, known as Bid A.
The council has said details of the bids are commercially sensitive, but it is understood an application has been received from hotel chain Premier Inn.
A decision will be made on the sale of the land at a full council meeting on December 2.
The Save our Foreshore group has mounted a rival bid to preserve the site as a public space - creating an area for entertainment and sports events including an amphitheatre called The Shell.
Leaders of the community led group are considering taking the council to court if it decides to sell Pier Field for commercial development.
Speaking at a meeting to consider the future of the site co-chairman Russell Sparkes said the council did not have to sell to the highest bidder.
He added: “The council has said the land must be sold to the highest bidder, but it can exempt that and accept offers for under £2m less.
“In the next two weeks we will make sure that every single councillor in the district understands this and have it put into black and white.
“Why is the council feeding information they can only sell to the highest bidder - if this is not declared then we will go to judicial review.
“If the councillors vote to sell the land I can say there will be the biggest court case coming up.”
A spokesman for East Lindsey District Council said: “The council will robustly defend the decisions it takes.”
The land was placed on the open market in March at the same time as it was listed as an asset of community value.
It followed a decision by councillors not to sell the site for development of a Premier Inn hotel, Brewer’s Fayre Restaurant and drive through KFC.
