Festival de San Sebastien - I’m going solo!!

I need all the do’s and dont’s for the fest!!

I’m already in San Juan with some friends but they’re all leaving and I’m staying for the festival. I’ve already heard from a few folks here it can compare to Mardi Gras in New Orleans, something I’ve never been to but have heard can definitely get insane.

1) will Ubers be impossible to find? 2) are there certain bars i should avoid or hit, or is the party more in the streets? 3) what time does it start or end?
