Where was the pilot for the love boat filmed?

The first pilot, The Love Boat, filmed in 1976, was aboard the Princess Cruises ship Sun Princess on a cruise to Mexico out of San Pedro, CA. The second pilot movie, Love Boat II was filmed in 1977 aboard the Pacific Princess also on a cruise to Mexico out of San Pedro, CA. The last movie pilot, also The Love Boat, prior to the beginning of the series, was actually shot on the Queen Mary in Long Beach, CA because this pilot was ordered quickly and rushed into production and they couldn't book space on one of the Princess cruise ships. Some on-board filming took place alongside in San Pedro, CA on board the Island Princess.
