Thanx for that info Karin. Sounds like a great idea hiring a guide for the day to take you lots of different place, but we unfortunately wont have that much time, maybe only about half a day to fit some culture in!!! Only 3 nites in Bangkok with the majority of that spent doing some final retail therapy before we fly home!!
And also thanx for info on BTS, but as I said we only have limited time in Bangkok. Although I did read, I think on their website, that you can buy day passes that were really really cheap. We will mainly use skytrain to get to Chatuchuk Markets.
Thanx again.
