Signage went up on the Renaissance Toledo Downtown Hotel last week as the revamped hotel gets nearer to its grand opening. The hotel has been closed for the past year-and-a-half for a major renovation that has involved nearly every part the property. Chicago-based First Hospitality Group Inc. has said the total cost of the renovations is likely to be about $25 million. When it reopens this summer, it will have 241 guest rooms, a restaurant, and a rooftop bar.
