Much of her interiors, including all five boiler rooms and forward engine room were gutted to make way for a 'Museum of the Sea' with the involvement of underwater explorer Jacques Cousteau. It was an incredibly ambitious scheme and ultimately destined for complete failure. Only a small portion of the museum was ever completed, and even that was forced to close within years. Today, the cavernous spaces left over serve as a reminder of the disastrous scheme, which not only have reduced her original interior spaces to a fraction, but compromised the integrity of the hull. She first opened as a hotel on 2 November 1972, with just 150 rooms and with 400 rooms by 1974. However, a succession of different private operators - including original operator's Diners Club, Disney, RMS Foundation Inc and Queen's Seaport Development, Inc - have failed to make a success of the Queen Mary. The latter operator ended up in bankruptcy court proceedings, over a rent credit dispute with the City of Long Beach, which dragged on for two years between 2005 and 2007. Today she is leased from the City by Garrison Investment Group and operated by Evolution Hospitality, LLC.
