The Rugby World Cup Sevens (www.hksevens.com.hk) sees teams from all over the world come together in Hong Kong in late March for three days of lightning-fast 15-minute matches at the 40,000-seat Hong Kong Stadium in So Kon Po, a division of Causeway Bay. Even nonrugby fans scramble to get tickets (adult/child $880/300), because the Sevens is a giant, international, three-day party. For inquiries and tickets, contact the Hong Kong Rugby Football Union (2504 8311; www.hkrugby.com).
