Magic: the Gathering in the UK
7am or a little later start from London in a car works.
There's a 9:07 train (19 GBP Advance fare) that gets you in in plenty of time but the last train back is around 8pm (if you play out the Swiss or Top 8 you will surely miss it with the 12pm start).
I also have an apartment in Bretby which is less than 2 hours from Liverpool by car says Google maps. It has two bedrooms. Deb and I can stay at her Mum's. So one single, one (smallish) double, a sofa and some floor space going spare. Splits the journey time to Liverpool approximately in half. So that might be very useful on the way there or the way back or both depending on how much you hate early starts, late nights and/or driving. Trains from my place to Liverpool and back take longer than London trains so staying at my place probably involves me or someone else driving (preferably someone else!)
What say you road warriors?
