The owners of Mt. Olympus Water and Theme Park in Wisconsin Dells have purchased the neighboring Treasure Island resort and related properties that will be incorporated into a single, Greek mythology-themed entertainment resort complex.

The purchase included Treasure Island, the Captain's Quarters and the Pleasant View Motel lodging properties, along with the Bay of Dreams Indoor Waterpark and the former Family Land Outdoor Waterpark properties, from Jim Mattei. All of the properties have been acquired by the sole proprietors of Mt. Olympus, Nick and Eva Laskaris. Terms of the transaction, completed March 15, were not disclosed in a statement issued Monday.

All of the properties will be renamed and upgraded to reflect the Mt. Olympus Greco-Roman theme. The renovation work will include upgrades to the Treasure Island lobby and guest rooms, the addition of a new family video arcade redemption center and an on-site retail store.

The 156-acre Mt. Olympus Water & Theme Park was created with the 2004 merger of Treasure Island and Family Land with a neighboring theme park that was co-owned by Mattei and the Laskarises.
