Seating just six people for each showing, this South American hotel’s year-old 7D Princess cinema flaunts an IMAX-style experience. Each film (between 10 and 15 minutes in length) screens about a dozen times daily. All of the senses are engaged, as the theater uses scent, vibration, and a little snow to enhance the experience. There’s also a 3D cinema on property, showing films like Godzilla and first-run movies, along with Bollywood flicks.
