The best thing about this software is that it can be used in any language as long you have good knowledge of English, French or Spanish languages only! It's easy to use but not so much user friendly.
We are using tiuL mainly because we manage lot more than one destination at same time with different companies which makes managing very difficult without having proper tool like TUI L.It helps us keep track how many people from our organization went through each place during their visit there by keeping all records under separate tabs within single window itself instead going back n forth between multiple windows. This saves lots amount of precious time while doing work.
