Interested in a day trip from Colombo to Sigiriya?

Hi everyone! I am not a real expat in SL, but I am based in Colombo for a couple of weeks for work. I don't have much time to actually visit places outside Colombo, but I would love to see Sigiriya. I know it is a bit crazy to do this in one day from Colombo, but I would like to do a day trip with Blue Lanka tours. As I am traveling on my own, it would be great to find others who want to join, so we can share the experience, (and the total cost of Protected content :-) ). So, anyone interested in a day trip from Colombo to Sigiriya before 1 December??
