A hotel in the U.K. will soon be offering stays in a Willy Wonka-themed room . . . with lickable wallpaper.    This is happening at the Chocolate Box, which is a chocolate-themed hotel in Bournemouth.  It’s on the southern coast of England, a little over 100 miles southwest of London .  In addition to the lickable wallpaper . . . in “a variety of fruity flavors,  there’s also a chocolate fountain with fruit and marshmallows for dipping, and bowls of candy that can be restocked at no extra charge.  The room key even looks like a golden ticket.  Oh, and you can take a bath in chocolate if you want to.  It’s actually not that expensive to say there, either.  It’s about 277 bucks a night.  But chocolate baths are extra . . . about $208 per.   And by the way . . . the lickable wallpaper is changed in between guests…
