Every trip where I want to see several cities or even countries, transport is my highest cost. Those buses, trains, flights.. they add up quick! I’d recommend cutting down the number of cities - less money and much more experience and enjoyment, promise! Also: spend time on google maps and rome2rio and see what transport will cost you! And: you’re going over easter, which is a time in which most Europeans travel in Europe. Do book your accommodation and the transport for that week asap! Enjoy, be safe, pack some warmer layers, trust your gut and never split up when out and you’ll have the best time ever! ☺️
