So you are talking mid-March? Easter is real late this year. That is when the snowbirds vacate.
Currently, the worst BJ in Laughlin is offered at the Mandalay Resort Group (now MGM-Mirage) properties of Colorado Belle and the Edgewater. The 6:5 BJ nonsense has infested most games.
The best games are dealt at the Pioneer and the Golden Nugget. You can play true $10 single deck with downtown rules at GN. They usually have a $3 shoe game too.
My favorite place for just for fun BJ is the Pioneer. The DD usually is $3 and single deck $5, with DOA and DAS. Don't think you can resplit Aces anymore.
Drink service is good at both. Craps is fun at both too...Pioneer usually is $3/10x and GN $5/5x.
The other River joints fall in between.
The Edgewater has a fun $15 buy-in BJ tourney on Weds/Fri.
