Alright mate,
If you're coming on your own from S. Wales, you'd probably be as well on the train. When you get off at Reading, go into the pub that's joined onto the station on the right hand side as you leave the station ( can't remember it's name just now). Rest assured it'll be packed with Villa. I wouldn't be surprised if there's not a few more on the train up either. There's a shuttle bus to the ground across from the pub.
Tbh, if you car it, it'd probably be a bit lonely, given there's no away pubs near the ground and the car parking is crap and dear.
If you go for the train option, message me and meet me and a couple of others in there if you want.
If you do decide you want to drive, then if you come off m4 J11 and head towards reading on the B3033 there is a big harvester pub on the right hand side.
Last time we played reading we drove and parked here for nothing and the pub was fairly busy with a good mix of reading and villa supporters.
Takes about 15mins to walk back down to the ground. Thats where ill be heading once the coach has parked up!!
