I-Itinerary is very easy to use and has a very good customer support. The customer support is very friendly and helpful, and the system is very user friendly. I-Itinerary is not user friendly, it's very difficult to use and navigate. It's a good system but can be improved. I am not a fan of I-Itinerary. I would rather use another system. I would say that I-Itinerary is a good system to use if you need to plan out some things and have a lot of customers. We use I-Itinerary to plan trips and trips. We use it to create a calendar with all the information for our customers.
