I know this is somewhat broad-but I know there’s a lot of people out there who are great with itinerarys and I need advice!

I leave Barcelona on 10/24 and basically need a route that will get back to Prague on 11/24—so that gives me a whole month! Here are the places that are a MUST on my list:

Florence
Venice
Athens
Istanbul/Ankara
Budapest

I am open to any other places that are a "must see" as well. My main dilemma is what route to take that will maximize stuff to see but is easy on my wallet. I am having a difficult time planning this because Turkey is fairly "out of the way"…but I really want to go there. I also don’t know what route to take to get from Turkey back to Prague-while including a stay in Budapest. Like I said, I am open to going anywhere that is worthwhile to visit. So any advice anyone can give on what sort of trail I should follow and whether I should take the train/bus/ferry would be so helpful! I am a first time female travelling solo.

thanks!
