(CNN) -- Twelve-year-old Peter Mance knows every street before he sets foot in a city. It's not because he's visited before. It's because he's autistic and has an uncanny ability to memorize maps. "He's actually a big help when traveling," jokes his mother, Kim Mance, founder of women's travel blog Galavanting and the Travel Blog Exchange, a community of travel writers and bloggers. Mance's other son, 10-year-old son Stephen, has used a wheelchair since surgery to remove a spinal tumor left him paralyzed from the waist down. Mance always has to make extra phone calls to ensure there's an accessible subway or hotel room, but that hasn't stopped her from vacationing with her sons all over the world.
