T.I. isn't a mind-blowing hotel but it does have its perks. First of all, it's usually cheaper than many of the hotels on the strip. Secondly, it's pretty center strip and you can easily walk to The Forum Shops or Fashion Mall next door.
We were in Vegas during what I would deem an off-peak season but the check-in line was still crazy long. It moved fairly quickly however.
This was my second time staying here. The first time the room was very nice and the beds were comfortable but this time we had the most uncomfortable beds ever. Our fridges barely worked and the TV remote was out of batteries. If you do get a Strip View Room though, it's a pretty amazing view.
There's cigarette smoke pretty much everywhere and you don't really have that nice perfumey smell that you get at Cosmo or Aria.
Regardless, I'd still probably stay here again because of the convenience factor.
