The three stars are for the value and location of TI. Whenever my Vegas-loving friends and I are in need of a place to stay, TI always seems to have the best deal without having to stay at the very north or south end of the strip or completely off strip.
TI's location is very convenient to first time or repeat Vegas visitors. Many of the other hotels, shops, clubs, restaurants, you-name-it are very accessible by walking.
The rooms are okay. They are average sized--they don't feel cramped, but I wouldn't call them luxury by any means. Clean for the most part. The air of the hotel is old itself and sometimes the non-smoking rooms smell like smoking rooms.
I wish there was better food options within the hotel. We are always looking for something quick and cheap to eat before going out or after coming home from a long night and TI has very little to offer in the food department other than the pizza joint.
