Since so much of the data is user driven, not all of the top tourist destinations have ratings and summaries, but with time that will change. The user interface is very easy to use, and I love that you can download the maps for offline use (for if youre traveling abroad for example). You can even create the maps on their website if you want too, which makes it a little easier to create maps. Since it syncs with Facebook, its super easy to share and collaborate with/on maps with friends youre traveling with (or send a previous map to a friend). Theres still little issues Id like to see resolved (google maps data isnt perfect and it has trouble finding some addresses), but on the whole, this was the best app I found for creating maps that you can use on the go without cell data/gps. With either of those, I imagine it would be even more helpful.
