Did you know that Mother Rabbit never travels to a city or country without reading the Frommer's Guide first? It is true. If I am spending the $ to travel to a new destination, I want to maximize my expereince and get the most bang-for-my-buck while I am there.
I am a huge fan of the Frommer's star rating system and I use it to select restaurants, make hotel choices and to decide which sights are most worth my time. Planning for a trip and studying the area enhances the anticipation, which is part of the fun.
If I had to rate all of my advice tidbits, this one would be in my Top Ten. If you are investing in a trip of any kind, purchase a Frommers Guide for the region and maximize your investment.
