As this was probably going to be the only time I was going to visit Disneyland Paris I wanted to make the most of it, so decided to buy this guide. I bought it a few months before we left to help plan the holiday and found it was absolutely inavaluable. It's really detailed and covers loads that your typical guide doesn't such as detailed map plans and instructions on how to travel with a family. It has information on how to beat the queing system, how to save money on taxis and really in depth recommendations on the restaurant.
The best bit about this book was the touring plans which was a bit like a 'Choose Your Own Adventure' telling us when the best times to go on the rides and which ones to skip. Loved it! We felt quite smug watching people suffer in queues for attractions that we had managed to experience hassle free thanks to the information in the guide.
I can't recommend enough how great this book is at taking the hassle out of the nightmare of navigating your family around a theme park!
