I'm planning to travel with my child to Beijing around the end of August and I'd like to know what are the suitable accommodation options for that period. According to the itinerary, we will arrive at Beijing West Station in the morning and spend the day visiting the Forbidden City and the National Museum. The next two days, we will visit the Summer Palace and the Temple of Heaven. As I've searched on Ctrip, most hotels are quite expensive. Could you please recommend some budget-friendly options or give me some suggestions on which platform I can find affordable accommodations? I'm primarily looking for options near the transportation hub.
