1st : Wait at least 7 - 10 days as a trial period before you try new keyword.
2nd : Replace your current templates to "Retro Purple"

dubaibusinesspost.com : i think most of the visitors come from here
http://search.jayde.com/cgi-bin/search.pl?a=0&query=DUBAI
Totally great .. so use it.
It looks like you using "DUBAI real estate" or something related as a keyword.
Try to use Overture tool to find the most "DUBAI" search queries done by people..
You can do the same with "everythingvacation.com" but i prefer to find vacation terms related to where most of your visitors come from. ( USA , Asia , Europe )
With term like "vacation" , try to focus on regions more than countries.
For example .. if most of your visitors come from France , England , etc.. use Europe instead of country.
Good Luck
