For a group of 10 arriving near midnight in early September, the most economical public option is the Shouhang Night Bus Line 1 (to Beidajie Station, ~50 mins, ¥30/person), then split into 2-3 taxis to downtown (total fare ~¥80-100). For convenience and comfort, we can arrange a private fleet of 2 seven-seat vans (¥50-60/person, 24/7 direct hotel transfer) to avoid late-night transfers.
