One London woman learned the hard way to double-check the room before checking out after an ill-fated weekend hotel stay in Guelph.

A 33-year-old woman was nabbed by Guelph police when she returned to collect some items she forgot in her hotel room.

The items? Crystal meth and cocaine, some $42,000 worth.

Police say staff at a west-end Guelph hotel found the drugs in a room Saturday after the people staying there had checked out. Hotel employees called the police, only to have a woman return to collect the forgotten haul.

She was arrested by officers at the hotel and is facing two counts of possession for the purpose of trafficking.
