Time to throw the kids a bone? After touring historical sites all day, you can reward them with a visit to this teen-friendly trio: Ripley's Haunted Adventure , Guinness World Records Museum and Tomb Rider 3D . It's a little cheesy, and definitely touristy, but a good antidote to slogging around the missions all day.
One admission gets you into the haunted house, museum of oddities and theme-park-style ride, or you can pay a reduced admission if you only have time for one or two.
