It's been a while since I've been to Vegas. I'll probably stick to 2-5 NL. Maybe play couple of sit and go's. Not really interested in longer tournaments since I'll be there with the wife. Thanks in advance.
your best bets are Bellagio and the Venecian. Aria will likely have some 2/5 games going too and has a great poker rate if you care about that sort of thing.
In terms of volume, Venetian and Aria probably are the best.
My personal favorite rooms are:
For tourneys: Caesar's
For cash play: Venetian
For best room overall: Aria
For loosest play: Planet Hollywood
Best tourney series: Venetian Deepstack
