I'm a french lakers fan since 1989 and for the first time of my life, i'm going to los angeles and see the lakers at staples center vs Denver Nuggets next month

And i've got 2 questions,
- How many times before the games the doors of the staples center are usually open ?
- I will be in the hostelling internationnal of Santa Monica and i wanna know, is it dangerous to take the bus alone by night at the end of game to go back to Santa Monica ?
