You guys are so awesome! Thank you so much for your amazing info.
I am very worried because I thought I would be able to find a bus or something for around 15 euros to Prague (I kept reading that you can do that) so I booked my flight without doing any specific Frankfurt-Prague research. I did it asap as i was worried that after I found that cheap ticket, it would go up if I waited an hour to do additional research (Seriously! I found tickets to Paris that went up $200 EACH when I waited an hour to check other sites!! I couldn't believe it). And now I'm stuck with these non-refundable, non-transferable tickets and no affordable routes to my primary destination.
Norm, the 49euro flight one way is the cheapest so far (thank you), but if my plane is an hour late, then I'm screwed.
For trains, I used the BAHN site and the cheapest fare was 400 euros for two roundtrips. That's $630!!!! waaaaaay too much. That could've been tacked on to the airline cost and gotten us tickets straight to Prague, but we couldn't afford that. so, now you see the situation I have gotten myself in. To any future travelers: learn from my mistake! it's hard when you are a first timer. I spent weeks researching europe and I was honestly under the impression I could travel in a little uncomfortable bus or something for around 15 euros each ($95 for 2 roundtrip) so I budgeted that. Now, I'm not seeing anything for under $350 (for 2 roundtrip).
Feel free to private message me with any tips (i don't know the rules of these messageboards). I am so so so so grateful to get your suggestions. I feel like I completely screwed myself on this and whatever help you may have will absolutely make my day/week/year!
It's my first time ever spending this much money (and taking a trip), I am nervous and must make this work.
