I require statistics/research results on the length of time and habits of people
searching for holidays/information on the Internet (Purchasing habits).
I aslo need the sources.  
Particulary I am interested in UK holiday searches using any of the
big search engines or indeed onsite searches?
e.g. When searching for a holiday of $500 - $1000 people will visit 5
sites and spend 20min on each site.
AND
When on (eg expedia) people spend on average 15min before
purchase/leaving and only 5% make a purchase
