Easy to remembrer.
This is one of those that will need both marketing and development for value potential. Current search, overture, and length suggest mid XX. Properly developed as you plan to do would bring the the value to mid XXX to low XXXX. The name itself is generic enough to provide more that just maps. You can create itinerary feautures, highlight sightseeing locations, hotels, bus schedules, train, air, and much more. Overall, opinion of this name is average to good as is. Good luck with your development.
