Once again, just use your street sense as if you were at your house. There are usually a lot of people at the hotel outside and about as well as on the bus.
Sleeping in the room, not a problem , lock the door as if you were at home.
No, there are many single moms who don't stay home all the time. I even know a married woman who would never even go anywhere without their husband even 30 minutes away such as kid's museum and the like, which has got to be the most pathetic thing ever. So, he doesn't want to go, they don't go at all. 9 years old their dd is, never even been to the B. Gardens near us.
Life is too short for that. But then I the old" How can you stay in a hotel room by yourself? or go out of the country? are you kidding me? I have always been a very independent person. What is sad is for my frined, if her husband should die before her or leave her, she would not know how to do things for herself. Not the role model I would want my DD to see.
