Thumbs up for Radisson. Very friendly staff, quiet gym outside 7-8pm rush hour, decent breakfast selection with egg station, responsive management and now all rooms fully renovated. Been too busy for a day tour excursion, but I suspect you'd struggle to stretch the tour for a day. Brunei, especially around Bandar, is tiny. You can walk from the Radisson down to the jetty servicing the water village, which is right next to the Yayasan shopping complex and one of the spectacular looking mosques. Best way of describing Brunei, is imagine every day being a Sunday morning. It's quiet.
