Got Oasis tickets for Manchester. Totally psyched about this. What do you all recommend for transfer? I can't leave Paris until very very late the night before or early the morning of the concert, which is at 15:30. My strong preference is for train but what do you all thing about these options:

1)Train Eurostar to London & then on to Manchester. But the best scenario there is ~7-12:15 total time, with 45 minutes transfer between St Pancras to Euston (seems doable if no delays...I could do the later next train arriving 1:15). This doesn't give me much time to dump luggage at nearby hotel and then take train up to Heaton Park though.

2) Fly CDG-MAN 11-12 (seems risky bc later start)
3) Fly CDG-BHX 9-930 then train to MAN Piccadilly
4) Fly CDG-LHR 8-9 then train to Man Piccadilly (too risky? not worth the bother?)

Thoughts? Back up alternatives? What have I not thought of?
