倫敦去巴黎 June 25 - July 5

HI~~ I will be travelling to London for business trip on June 25 and will need to be there for work until June 28. I am looking to travel to Paris as well. Since I am travelling alone, I would like to see if there will be anyone going there at around the same time and I can join them? :-$

I am 26 female, don't know how to type Chinese, but can speak and read it.
