The best about it is it's customer service support that I have ever came across in my life. It has excellent tutorials/ help guides available online as well but there are certain features that you would find them more comfortable with than others. For example; booking hotel tickets or making restaurant reservations can become confusing if you don't understand what to look out for in the options menu. Having said this, however it was nothing major. At first sight, its user interface seems very different from other travel apps i've used so far (buttons/ icons seem similar though). Definitely use it! We made a lot of improvements on efficiency by using trip see concierge instead of asking each staff member individually. The ability to have everything in one place makes it easy! I wish there was more communication between me as an owner of my trip with other travel agents who are working through this system but that is not something we can change about our service so far has been good!! We love using them because they make managing trips easier than ever before by having all information at your fingertips when you need any info or just want some help from someone else while traveling.
