When Shirley is waiting nervously for Jane to pick her up to go to the airport, she says "Jane is picking me up at 4.00", this would mean the flight had to be around 6 or 7 o'clock at the earliest, even with just a 2 or 3 hour flight they couldn't have arrived on the Greek Island until at least 9 O'clock at night.Yet when Shirley arrives at the hotel it is broad daylight.
