Holiday (2009)

Miranda cannot be bothered with all the hassle of foreign travel so, telling everybody she is off to Thailand, she books into a local hotel. However she is rumbled, first by her mother when she goes home for more clothes and then by Gary's boss Clive, who turns up as her escort. There is compensation when she is mistaken for a high-flying conference attendee called Amanda and hits it off with the organizer, but when the real Amanda shows up there is nothing for it but to climb out of the nearest window.
