My wife is headed to Beijing for 6 days in early July and is having trouble deciding on a hotel and tour options. Looking at the Marco Polo, Grand Hyatt, and a few others. Wanting to keep it on the cheaper side though ($80-$120). She has a bad ankle so unfortunately can't walk too much, taxis are probably her best bet, but she's wondering the best way to get out to the Great Wall without it costing an arm and a leg or stopping at every other jade factory.
