Hello Pammi,
First of all , you are welcome to Jordan.
Jordan is one of the safest spots on earth,it is very safe to be here, however, people here have the habit of staring at strangers (specially hot women).
No one will ever attack you here, but you might hear some bulleing from little kids ...i hope not though.
You can hang out anytime you want, even at 3:00 AM.
there are many nice people here,
But also be aware of Taxi drivers, they sometimes over-charge tourists, make sure to force him to open the meter and never pay an extra fee.
Also, Never be afraid of saying NO.
