A party of four senior aged people is arriving in Tianjin by Cruise ship and spending nearly two days in port. We would like to visit Beijing and The Great Wall in one day if this is possible. Would we be able to hire a large car with an English speaking Driver/Guide who could show us these sights on the first day and then the sights of Tianjin on the shorter second day? If so, what would be the approximate costs for such a service?
