It just so happens that I bought a used iPhone and the previous owner did not delete the access passcode. What should I do now? Is it possible to bypass it?

Hi everyone! I'm looking to go to Las Vegas for my birthday. I'm not sure what to see, where to stay, or where to eat. Also, I don't have a car so it would be helpful if someone could suggest a hotel near the Strip. If not that, then where should I stay if I want easy access?
