PlacePass offers listings and price comparisons for more than 100,000 tours and activities in 800 destinations. The Cambridge, Mass.-based company was co-founded in 2016 by Ethan Hawkes, a former consultant with McKinsey & Co., and Emily Bernard, former vice president at Foreign Policy magazine. Eamples of activities listed by PlacePass are a picnic in the Grand Canyon, a tour of U.K. filming sites of the TV series "Downton Abbey," and the chance to cook pasta with an Italian chef in Italy's Tuscany region. Marriott appears to be taking a cue from companies such as TripAdvisor and Airbnb, both of which have branched outside of their core businesses to invest in in-destination listings services.
