but let me give a GOOD advice.: if you have options, better go ON YOUR OWN because:
1. you depend only on you and few other passengers--bus ride can be inpredictable..
2.you get there far before the buses do! So, if i were you,i'd be there at noon, then check the line in front of the stadium, then get something good to eat (but Wien IS EXPENSIVE- i recommend kebab on a stand-only 2.80€-surely the cheapest food and good cure for hunger..), then come back and go straight into first couple of lines!!!!
Now that all of you are going, i might fight for this ticket instead of Munich...
