So we are seriously considering our first ABD Germany trip for 2013!!!!! It seems that Dreams Unlimited and Costco have the best deals. We are a family of 5 so do we need to make any requests regarding hotel rooms? Are there any pitfalls that we need to worry about? How do we best book airfare so we don't lose money if the trip is cancelled? I assume trip insurance is a must but do we need to buy it when we put down the deposit? Thanks for any advice.
