I am planning to visit the 2nd Annual World Conference of Well Stimulation and Enhanced Oil Recovery on May 16-19 2011.

(Q1) If I add an extra 7 days to my trip, where would you recommned I visit as a tourist (NB: I have already visited Beijing twice on business but nowhere else).
(Q2) Please can you provide me with names and contact details of a few 4 star hotels during the conference?
(Q3) Please can you give me the contact details in UK where I can arrange a flight to Chongqing from London, UK?

many thanks
