Walking in the daytime yeah, walking a bit buzzed in the daytime, idk. Walking at dusk, yeah. After dark and buzzed? Probably wouldn't recommend it. No sidewalks.
There are some people with stands, but for the most part are not pushy, especially if you are across the street from them.
Route cabs have red plates and are marked on the side as such and are a decent way to get around. Be forewarned about using a white plate though, they are not licensed or insured to carry passengers.
HTH and enjoy your stay.
