I was unfortunately on the prior cruise that had the water leak causing the electrical malfunction. The problems were in the front quarter of the ship only, and began around 7:17 - 7:30 the night before debarkation. We were all in the the Tropical Theater waiting for the 'farewell show' when the lights went out. CD John and Katrina did the best they could, but after about 20 munutes or so of jokes they said that there was a electric failure and to quickly and in an orderly manner to leave the theater. Once we left and went to our stateroom we noticed that everything in front of the fore elevators were pitch black. Our room was down the lighted hall about 10 rooms from the outage. I do not know how or if the passengers were able to use their pass card to get in their room, or if they could do anything once they got in. Also during thi first hour or so, all air conditioning did not appear to work anywhere, but that was remedied. The television never worked after that. Later that night the captain announced that the problem was more severe than originally believed and said it would take awhile to correct but the ship had power to enter the mississippi to NO. That was the last announcement we heard. In the morning everything in our stateroom was still workiing and when we checked out, the front was still pitch black. No one seemed to knw what was happening at that time.
