With 62 apartment-style suites, the hotel occupies four floors of The Battery, a $154 million redevelopment of a historic Delaware River Generating Station. The hotel, which started accepting bookings earlier this week, makes Rivers the third casino in Greater Philadelphia to offer hotel rooms to its customers. Rivers Casino Philadelphia opened its luxury boutique hotel, Riversuites, at the renovated PECO power plant on the Delaware River waterfront on Wednesday, with a grand opening ceremony.
