I love being able to use one app instead of multiple! It's easy access from my iPhone or iPad so that is really convenient when traveling with it in hand. There are times where there isn't an immediate answer but if you keep checking back within minutes they get back to you! Sometimes things don't always work right away (sometimes takes more than 1 attempt) which can be frustrating at first until you realize this is just how their system works. We've been using them now about 4 months since we started getting answers quicker as well as improved communication.
