The main thing I think you should change is the font. Other thanh that the site is genherally okay. Try and get some ideas from domain.com.au (Australia's largest online property site). Good luck with your site.
Nice logo design I think the overall layout kind of looks "boxy", what I would suggest is add rounded corners around your tables.
Make the links change the color on hover and change the font. Also, if you put some information into a table, try to use table style="blahblah... etc to make it look thin and pretty. Just a suggestion.
I liked the overall design. To me, when the site is restricted to a certain width, it should have a visible border around the content. That is my only suggestion.
It is a very good site mate. Lots of information. However I have noticed few things that may need a second look: 1. On Mozilla Firefox, the layout is aligned towards left. The extra large white space on the right hand side doesn't look professional. 2. I counted 81 "Hua Hin" on the home page. Is it a SEO technique? I don't know. What CMS you are using? Try to see if you can integrate some cool tools like these these on your site. 1. http://free.akawe.com/index.php?option=com_hotproperty&task=view&id=1&Itemid=27 2. http://www.monoslideshow.com/ With little catchy front page I am sure your site will rock!
