Holiday Scams
Scammers are taking advantage of high holiday demand by creating supply that doesn't exist. There have been reported cases where travellers book accommodation only to arrive at the destination to find out it doesn't exist, or it looks nothing like the photos they saw online.
Always watch out for a listing that seems to be too good to be true. Do your research and look out for (genuine) reviews from other travellers. You can also verify the address of the property you are booking using online maps and web searches.
