If youre down, you can stay at the greyhound on 7th street in downtown, near skidrow. A lot of people might tell you that it sucks and its aort of dangerous but its not that bad if you have common sense, you can skate to lafayette skatepark from there, its like15~20 minutes away but theres some well known spots on the way there and a lot more around the park, theres a bunch of others spots around the area and you can hit up wilshire and look up more shit all within skateable distance.
Cheap hot dogs any other corner, bunch of mexican places, AND IF YOURE SUPER LUCKY, you could ger blessed with a "momma" sighting, she's like lafayette's locals grandma, she looks after the kids and hooks everyone up with some fruit, water, donuts, or coupons for free meals(no purchase necessary type of coupons) coolest shit ever.
Or you could just rent an air bnb, uber anywhere and have a boring ass time at hollywood high
