Hotel Mario

Hotel Mario was a computer game mostly known for its poor voice acting and bizarre format. In this game, Bowser and his children take over the Mushroom Kingdom and built 7 resorts on it. The Princess is held captive in each hotel until the moment of its destruction, at which point she taken off to a different hotel. Each hotel is run by a different Koopaling (except for the last one which is run by Bowser) whom must be fought by Mario in order to destroy the hotel.
