Srilanka is one of the best and most attractive place to visit everywhere .I didn't know about this but i think it is one of tourists company which always guide you.You can find driver for you,i hope.

We used BSL to book our trip five years ago and had an excellent experience with them. I'll use them again.. Be forewarned that the Xmas period is the most expensive time of the year to travel. Hotel prices often double (or more) during that time.

I, too, used BSL. See http://www.fodors.com/community/asia/thursdaysds-boutique-sri-lanka.cfm

There are other companies with similar but cheaper programs, such as Red Dot.
