Who are these tips for? I value my privacy and safety, but for tourists or normal business travelers these seem paranoid.
Here are a few tips for regular people: Check-in early (by phone or via web, if you need to) because the best rooms are allocated on first come basis. Always insist on a top floor room otherwise you'll be constantly disturbed by a heard of elephants walking across the under-engineered floor above you. Avoid the ground floor, for the reason above, and, also it tends to be where they put the most likely trouble makers, groups and smokers (who'll noisily leave and enter their room throughout the night for regular nicotine fixes). Make an official complaint for the slightest of disturbance, budget hotels are built on the cheap with a contingency for refunds factored in - you'll be surprised how easy it is to get a full refund and/or a complimentary breakfast. If you hear a fire alarm do not hesitate to vacate the building and stop for nothing, construction standards meet the minimum fire safety regulations and no more. This means the building can lawfully burn to the ground in less than an hour, and a few have done exactly this.
Top tip, have a short nap as soon as you arrive. It helps alleviate that 'first night in a strange bed and can't sleep' problem.
