Travel to Beijing … suggest staying in the same hotel for a few days or staying separately …

It depends on how your schedule is arranged. If you are going to the suburbs, you can book separately if you can't come back in two or three hours. (If you have, it is recommended to take less luggage) Where to play and where to live;

If you are traveling around the city center for a few days, just book the same hotel, it will be more comfortable, and you don't have to bring your luggage to play.
