Basic rooms typically have four walls, a bed and a fan (handy for keeping mosquitoes at bay). In the cheapest instances, the bathroom is shared. Most places geared to foreigners have Western-style toilets, but hotels that cater to locals usually have Asian squat toilets. Air-con and private bathrooms cost more. Camping is not a widespread option due to the tropical heat, but dorms are becoming a more economical option – especially in the Philippines, Singapore and Thailand, where accommodation tends to be more expensive.
