How early should I plan my trip to Europe?

Generally speaking, it takes one month in advance to see which countries in Europe, Schengen countries, Britain and other countries you are going to. If you want to travel to Europe, you must never join a tour group. The experience of traveling with a group is too bad now. Self-funded projects, shopping spots, catching up with the trip, the whole trip is very tired, and now you are more comfortable. You all choose customized tours. Sinbad tourism is customized, saving time and worry, as long as you arrange other routes according to your needs, it will not waste time. It is especially suitable for business people who are usually busy with official business to travel for leisure. Of course, the price is above the average, but as far as service is concerned, it is definitely worth the money. It's completely different from ordinary group tours. I hope I can help you.
