Warren the 13th and the Whispering Woods

"Twelve-year-old Warren has learned that his beloved hotel can walk, and now it's ferrying guests around the countryside, transporting tourists to strange and foreign destinations. But when an unexpected detour brings everyone into the dark and sinister Malwoods, Warren finds himself separated from his hotel and his friends--and racing after them on foot through a forest teeming with witches, snakes, talking trees, and mind-boggling riddles"--Amazon.com.
