Stayed at Mandalay Bay for 5 day for a conference and played as much poker I as I could in between.

Mandalay Bay poker room is nice, clean and friendly, but small. They spread mostly 6-12 Hold-em and up, with 2 or so NL tables. Played a few 30 player tourneys, these are good. Meet mostly tourists at the tables. Good staff and dealers.

Luxor poker room is a little bigger than MB, but not as good in my opinion. They spread most low-mid limits and their tourneys are a big crap shoot with not enough chips to start. Will not play here again.

Excalibur poker room is easily triple the size of the other two rooms and is a little worn down, but a good place to play. I liked their 2-6 Hold-em limits. Did not play any tourneys here. Will definitely come here again.
