I've stayed at TI resort for a week. I was in room 14 (deluxe) for 6 night and in room 4 (standard) for 1 night.
Both rooms need to be completely renovated even if every furniture are working, but both rooms look really worn.
The swimming pool is great when it isn't crowded.
Food is good and constant in term of quality.
My opinion is that you can find much better deal around baloy beach for less bucks.
