Cambodia Accommodation
Western-style accommodation is generally only available in the big tourist hotspots of Phnom Penh, Siem Reap, and (to a lesser extent) Sihanoukville. Basic guesthouses can go as low as US$2/night in the countryside but prices in the cities are usually in the US$5-10 range. At the budget end, expect to provide your own towels etc.
If you want air-con and hot water, the price creeps up to close to US$20, and you can easily pay over US$100/night if you want to stay in a branded five-star hotel.
