• Merged under one roof are now three oddballs of family fun…Ripley's is a collection of the hard-to-swallow and bizarre, such as the giraffe-necked woman of Burma and the double-eyed man of China. – Frommer's
• …the Ripley's has rooms where everyone can look at different things at the same time. The kids kept tugging at me: "Mom! Look at this!." Lots of weird and interesting things to see. – akidcagal, TripAdvisor
