Have booked a few days at the BaliHai on arival on 19 May and then 5 days at the Tegal Sari in Ubud (Room 24 sounds great). We are then planning to have 6 days somewhere like the Griya Santrian in Sanur. I have not booked anything in Sanur yet and was wondering if it would be better to try for a walk-up bargain. Any advice?
