I've stayed at the T.I. a number of times in my life and, I must say, the place has taken a turn for the better. The rooms are newly remodeled- complete with flat screen TVs and very sexy decor. The casino is moderate size and there are some really good restaurants to choose from- my favorite is Isla.
The best part about my stay at the T.I. was the pool cabana that we rented. The price was really reasonable for an entire day and we got unlimited non-alcoholic drinks, a flat screen TV, our own cocktail waitress, and a great place to hang out by the pool. I definitely suggest that if you want to sit by the pool for a day in Vegas, a cabana is the way to go!
