Travelodge has declined to comment on speculation that a private equity firm has made a takeover approach worth up to £750 million.
BC Partners, which owns Fitness First, is reported in the Daily Telegraph as being in the process of putting together a formal bid for the budget chain.
But the newspaper reported that US investor Starwood Capital could also be interested by buying Travelodge along with Premier Inn owner Whitbread.
Travelodge is owned by private equity firm Permira.
