If you'd like to save some cash on your trip to Grundlsee, then listen up! As every experienced traveller will tell you, don't leave booking until the last minute. Prices are usually highest just prior to the departure date. Also, look around online and compare your options. If your destination has multiple airports, you may be able to nab a fantastic price by flying into one a little farther out. Last but not least, another easy way to save some cash is be ready to book fast. If you stumble on an amazing bargain, don't hesitate --- snap it up while you've got the chance.
