22 days trip - Eastern plus abit of Western Europe

[mixtape]

I'm wondering if the below itinerary is doable for my 22 days trip in europe in august - sep next year..

My starting and ending destination will be Vienna:

1) Upon reaching Vienna, i'll be taking an overnight train on the same day to Krawkow (Krawkow for 3 days)
2) Krawkow - Prague (by train, 3.5 days in Prague)
3) Prague - Manchester (by BMIBabby, 1 day) --> i have to be in Manchester on at least one of the saturdays
4) Manchester - Dublin (by Ryanair, 4.5 days in Dublin)
5) Dublin - Berlin (by Ryanair, 4 days in Berlin)
6) Berlin - Budapest (by Easyjet, 1.5 days in Budapest)
7) Budapest - Vienna (by train, 4 days in Vienna (including a trip to Salzburg)

i know i'm flying all over the place.. but that's the only way i can factor in the cities i want to visit.. ryanair dont fly into vienna , easyjet dont fly into dublin or manchester , BMIbaby dont fly into Berlin ... for the train, i'll be buying the European East Pass - 5 days tix.. i'm estimating the cost of the air tix and train here to be around 450 euros..

by the way, the manchester trip is a must as i wanna go for a soccer match assuming the match is on a saturday or sunday (and a home match at that!) will have to wait til when next year's schedules are out.. hehe..

any suggestions to get me out of this mess or a cheaper way to get around? or is this fine??

thanks!!
