I might add that if you venture toward Rickmansworth / The Chilterns etc in earxh of "Wemberley, Wemberley"...it would probably be better value heading toward Waddesdon Manor for a grand day out and watch the 'Replay' anon! Association Football - aka soccer - is a load of balderdash anyway.
Exeter will be at Twickenham on Saturday...now; that might be a contest '+'. Enjoy Wembley - and if all else fails, the shopping complex alongside, but a few minutes walk away, has a 'ProCook' branch with lots of bargains!
