is 2 nights in bandar seri begawan enough?

Two nights can work well for a long weekend in Bandar Seri Begawan. The main attractions are centered around major landmarks such as the Omar Ali Saifuddien Mosque, Jame' Asr Hassanil Bolkiah Mosque, and the Royal Regalia Museum. Flying into BWN airport for a short stay gives you time to see these highlights along with Istana Nurul Iman, the Brunei Museum, and the Brunei Darussalam Maritime Museum.
