If you had to choose one of the many Hotel and Casino's to stay in on the south end of the strip I highly recommend Mandalay Bay.
Pre-baby trips to Las Vegas changed our viewpoints about where to stay while in town and we often found ourselves staying in T.I (not that that's a bad thing at all) but since we were in town with our little tyke we decided to splurge a bit and stay here for a couple of days after already staying a couple of day prior in another resort at little to no cost. Shhh, I'll fill you in on that in a minute.
From the moment of check-in throughout our entire stay the services they provided had me very impressed-as I should be right? Sure it's a pain to weave your way through downstair's to pick up your car from valet but that's a miniscule oddity. On the upside they work miracles on expediting.
Mandalay is a beautiful hotel as is, connected to The Four Seasons, with it's man-made beach and puny wave generator but they also have great shops, excellent dining choices and lots of entertainment to choose from.
