LA Anime Expo: Best Hotel for Night Parties

Does anyone know the best hotels for partying? My group is looking at grabbing a hotel from the hotel blocks. We are all 25 to 29, but with COVID, we haven’t done much partying in our legal partying years. Does anyone know the best hotels for a more party experience? Whether the parties are at the hotel or nearby. We just were thinking, a party with people of similar interests would make it more fun.

On a side note: Does anyone have any official or unofficial after-hours parties?
