Was there on Dec 23rd 7 pm - Dec 24th 7 pm. Hopped casinos from Plaza to Taj and went over to Borgata.
Caesars, WWW , Plaza, Resorts , Showboat can be literally closed. They all have one BJ pit with what 4/5 tables on the main floor and one or two tables in the high limit. Not sure where the HL room in Plaza is - have not seen. Bally's was a bit better , not as bad as others.
Taj's bj its was a bit crowded late nights , but the winner seems Borgata. They still had to close several BJ tables - the 10$ ones near the open parking entrance were closed, But the other side was full with a lot of crowd.
