Everybody and their brother will be in Tunica in January for the two sets of tourneys going on at the Grand and Gold Strike.
If you're interested in live tourneys and are anywhere close it's worth the trip. but book your room ahead of time as the hotels will almost certainly be sold-out.
Lots of the 'famous' players such as Negreneau and Greenstein, etc are around for the $10k events for those who are interested in that kind of stuff too.
But there are many tourneys smaller than that going all the way down to the $175+$25 that is usually held at 5pm daily at the Grand during that stretch as well as 2nd chance tourneys at Gold Strike and all the SNG's and satellites.
It's 3 weeks of poker crazyness in Tunica and it really is a pretty fun time. Jan 4-25 I believe.
As for Tunica tourneys not in January....lots and lots of them. Horseshoe does a good job running their tourneys imo.
Gold Strike isn't bad either although sometimes their structure is faster.
msgaming.net looks like they keep their Tunica poker tourney schedule updated pretty well.
