Is anyone else stupid enough to be attempting to attend both? Cardiff or Portsmouth?

I've got a lift from Bristol Parkway to Wembley and back, and my mate reckons based on the semi-final we'll be back at Parkway by about 7.30 - 8.00 (assuming no extra time etc).

At the moment it'll be train to Taunton and then a choice of £45 taxi or ages on a bus. I'll be back for Battles but if anyone else following either team has any plans I could get in on, that would be pretty great. Ta!
