Luton away

Planning to go with son and maybe nephew. My weekend depends on getting tickets; then I'll book/arrange transport/accommodation/lash-up with old cockney cronies and sightseeing with my son. Haven't been to away match for a while so don't qualify to buy ticket on Friday or Monday. I'll try Tuesday. Could be sold out I guess, as relatively easy to get to compared with some of the games this season. Anyway, "my glass is half-full", so I'm optimistic. I'd be grateful if any-one has any idea of my chances so I can plan the rest of weekend with more confidence?
