I have visited the museum in Manchester. 4 hours is more than enough time. Displays are mostly tackle and flys. Classic memorabilia, bios of famous flyfishing noteables and a gift shop. Typical museum experinece. Facinating for me..not so much for the family. Bring your glasses as many of the displays require reading small print. Also make sure you stop by the Orvis headquaters store...Nothing really new there but a cool store. Manchester also offers several outlet stores and the world's best candy store Mother Myric's. All downtown within walking distance of Orvis. Used to have a ski house nearby in West Waedsboro VT. Good Luck
