We incorporated Megan's detailed advice and suggestionsin our itinerary planning.

 For crowdsourced advice, the Norway Travel Tips, Advice & Planning group on Facebook is an excellent resource. I relied heavily on its search function to cross-reference recommendations for local hotels, restaurants, transportation, and tours while planning our itinerary.

I felt some peace of mind having a folder of Norway-related apps on my phone for tickets, reservations, and general info.

• Currency app
• Google Translate
• TravelBoast, an app to show off your trip in a fun, animated way.
