How essential is a VPN for travelling?

[Boone]

I would be traveling to America from Germany and few of my friends have recommended me to use a VPN because of all the cyber attacks and identity theft cases on the rise in America. If the magnitude of this issue is on the rise, I can renew my subscription with Ivacy VPN. Kindly help me out here.

Eh if you can renew it then do so, but would it not make sense to find out how these hacks happened first
