Hello - I will be visiting Bangkok for a few days in April this year for the first time. Because of my limited time there I thought it might be a good idea to get a private tour guide for a couple of days to make the most of my time in Bangkok. I found a particular tour guide website through the main Utopia site (http://bkk-tours.com) and was wondering if anyone had used their services before as I can't seem to find any reviews on the web or searching through various forums.

Thanks in advance for any advice you might be able to offer.
