What Should I Do in Las Vegas?

I'm currently on a Delta flight in first class (thanks to my Diamond Medallion upgrade clearing 6 days in advance) and will be landing in Vegas in about an hour. And not surprisingly, I haven't done much planning on what to do. I haven't been to Vegas since a quick mileage run last December, when Expedia.ca was giving away trips for free! Too bad my blog had a fraction of the readership then, because I imagine many of you would have gotten in on that amazing deal.

Anyway, for my trip I'm meeting up with my friends who live in Spain and several are going to Vegas for the first time, so I want to go to a couple good meals and show them a good time.

I'm staying at the Palazzo, because it's a new member of Intercontinental Hotels and I'm very curious to see how I'm treated as a Royal Ambassador. I've heard through the grapevine that the free mini-bar includes bottles of Moet and Grey Goose. As much as I want to try some of the newer Vegas hotels like the Mandarin Oriental and Cosmopolitan, the Palazzo had me at a possible upgrade, lounge access and free top-shelf booze.

I fully understand it's going to be unbearably hot and I've had a good amount of pool time this summer, so I'm open for ideas of things to do during the day as well. You all know I like good food too, so pile on the recommendations!

I also enjoy playing Texas Hold 'Em- what's the best hotel for that?

Sorry for being such a procrastinator, but life's been busy! What are the best places/restaurants/clubs/random things to do in Vegas on a Monday evening/Tuesday/Wednesday in August?

Expect a full report when I'm done (though follow me on Twitter for live updates), though some things may have to stay in Vegas.
