Internet cafes have real name system all night, no temporary card is not good, in McDonald's should be good, to a cup of coffee placed there, things hidden well, mobile phone to read novels, if there is a book then can also go online, after midnight you can lie on the table to sleep!
Don't care what others think of you, I once spent a week at McDonald's, sleeping at night, washing my face and brushing my teeth, and going out to do what I should do during the day. PS: To prepare a very thick coat, the cold is very important, it is best to take more than one, the stool spread one, soft ah ~
