If I stay in a mixed room in a hostel....what keeps other kids from stealing my things while I am sleeping?

Crazy glue around your bed?

My husband stayed in a hostel and they had security cameras in all rooms except the bathroom.

mouse traps!

If there's a locker, you can use that (but bring your own lock). You can use a moneybelt to sleep with your passport and money, and assume that no one is likely to steal your clothing. Thefts at hostels are not particularly common, but I wouldn't leave any electronic devices or jewelry around. I'd also arrange to get a place with a locker.

Some people wear their money belts at all times, even take it into the shower then put it on a hook there. Some people use various methods of locking backpacks and/or chaining them to something.

I suggest you read over on Lonely Planet's website their forum called The Thorn Tree which has loads of people who travel the hostel and backpacking way.

Thank you very much to you all
