The Arena Racing Company (ARC), which runs the Royal Windsor Racecourse, has submitted plans to build a 150-bedroom hotel at the Maidenhead Road site.
The four-storey hotel, a Hilton Garden Inn, would have a restaurant and bar plus a fitness suite. It would be open all year round as well as offering accommodation to stable staff on race days.
The local council is set to grant planning permission subject to agreeing conditions in relation to transport and the likelihood of flood risk in view of its location on the flood plain of the River Thames.
