One of the most helpful apps we have used in planning our travels is Tripit, both the desktop and mobile version. It's easy to use and it organizes our travels in such a way that we can share it with family and friends. You can also plan for multiple trips as the itineraries are grouped according to travel dates and location. It's as easy as one-two-three.
1) Go to tripit.com and create a free account using the email address that all your travel related reservations are sent to (hotel, airline, cruise, restaurant reservation, car rental, etc).
2) After verifying your account, forward all your reservation emails to firstname.lastname@example.org.
3) An itinerary is created and indicates date of arrival and departure of all your travel plans. It also includes the address and a map if needed of nearby transit or driving directions. You can then share it with family and friends by forwarding to their email address.
Our parents especially like the last notation of sharing. Instead of having to forward each reservation separately, they are able to see all our travel plans in one place along with address and phone contact numbers. The only caveat is that while internet service is not needed for a simple view of your itinerary from the mobile app, you want to make sure your phone battery is good. We had a mishap during our last trip in that I (Sharee) had the mobile app but my phone battery was dead (literally). Rhonda went online to view the website version, but we couldn't get any internet service at the lower-level of the airport and she was unable to retrieve the address of the hotel. Thankfully, information services at the airport ground transportation was able to help us. Whew!! Point: you never know when technology won't work....make a back-up paper copy as "Murphy's Law" is still in effect. :-)
