Is it a bad idea to go to a school an hour away?

I have four options of schools that I could go to for sixth form, I can go back to the school that I already go to but they couldn't fit the subjects i wanted in the right box so i cant do the subjects i want to (and its an all girls school). I could go to a college not to far from my house, but this college doesn't have the best reputation, and all of my friends are going there and i want to start afresh and meet new friends. There is also a school out in es that i could go to but that is quite far away, but they have a coach to take you there. The bad thing about that one is if i have to do something after school and i miss the bus i have to get the train, i don't know what to do because es is countryside and the train station is nowhere near the school. The school that i really want to go is in north london (i live in east) and its a half an hour journey in the morning because my mum will drop me to the station, and an hours journey in the evening. I don't know if this is too much of a journey for me, which sixth form would be the best for me to go to?
