Have Family member there for 5 days so far. Many in her group have had phones stolen, money taken, card information compromised with charges taking place right away all over globe, attempted pickpockets on subway using the getting sick technique while someone grabs your wallet/phone. Someone even had laptop stolen on the plane prior down to landing or shortly after arriving in airport. They think on the plane. That is gutsy.
They are having a good time but all the internet crime reports are true. Be careful.
