Is staying in Sanur an option? Or just look around close to the area you want to be when you get here? I think there are a lot of cheap places that probably don't have any kind of web site. Look out for the short time places though:
Bali News: Dark Under-Belly of Bali Small Hotel Operations
Interesting article.It does not happen in Denpasar only,i have seen the same thing in Candidasa and other places.
The journalist should take some lessons in arithmetics though:
While many of the hotels, such as some found on Jalan Pidada, Gatsu Barat and near the main bus station of Ubung have a steady flow of family and small groups of domestic travelers that, according to the Bisnis Bali report, only sustains an occupancy of around 20-40%. And, while a 24-hour rental of a modest room with en-suite bathroom and a television can net between Rp. 150,000 to Rp. 200,000 per night (US$15-20), a short-term rental of only two hours can net between Rp. 25,000 and Rp. 35,000
(US$25-35).
