Detailed Train Itinerary for Ultimate Eurail/Interrail Vacation

I am a solo female traveler who likes to explore on a moderate budget; I think it's important to recognize that some opportunities when travelling will never arise again, and it's worth shelling out for them! I prefer to travel very fast-paced, and my guides will reflect that. In order to accomplish this, I have done lots of research about every place I have visited to ensure I use my time wisely. I have only travelled around Europe so far, but I am hoping to expand my horizons in the coming years :)
