This is a loose collection of different tips and tricks that I personally find helpful while visiting the Parks..

• You don't need to show up an hour early to get good places the watch the parades or even the night time spectacular (Disney Dreams (of Christmas)). There is almost always plenty of space and the "side arms" of Central Plaza are an excellent place to watch the fireworks
• Even if you visit more than twice a year, you don't need an annual pass, especially if you are travelling with family. Most times the cheapest way to visit is to book a stay "on site" at one of the cheaper Disney Hotels during the off-season. We usually end up paying about 600-700€ for 3 adults and three days in the parks. Considering that the cheapest annual pass costs about 300€ per person and doesn't offer Disney hotel benefits like early entrance to the parks, it's hardly worth the hassle.
• If you're in for breakfast in Disney Village, skip McDonald's or New York Style Sandwiches and head to Earl of Sandwich. It is usually not crowded and the English Muffins are way better than those from McDonald's. Plus you have a nice view at Lake Disney.
• Please don't stress too much about having an thoroughly schedueled itinerary of all the attractions you want to do on your visit. Check wait times with the official Disneyland Paris App (or for more advanced users use athird-party app) and queue whenever wait times are low.
