Traveling overland has a major advantages see different places of the European continent, stopping off along the way. You can save money, since flights from North America to Amsterdam, London, or Frankfurt are usually the cheapest. You should keep in mind that bus or train in Europe are not cheap, so it is reasonable to calculate the cost of the entire trip before you decide which route to take. If you do not want to visit other countries or do not enjoy traveling overland, your option is flying directly to Poland. the airline tickets in September are a little cheaper than June-August, but not that much. lots of really low cost airlines flying to Poland from the UK and flights from the usa are pretty cheap.
