TBH, if I could do it for one season, I might have given it a go. But am assuming that the 1882 tickets are under the same conditions as other season tickets, ie you won't be able to change it once it is allocated.I said elsewhere, although 1882 is not for me it might be worth it for some.
Assuming the cheapest ticket you can get in your phase is £1125, the 1882 ticket is £1075 more expensive.
If we get 5 home cup games at say £20 a pop (will probably be be less but for arguments sake) that is £100.
Your ticket is now £975 more expensive.
If the pre-match food, half time drink & free programme have a value of £20 that is worth another £480 (24 x £20).
Your ticket is now £495 more expensive.
You have the convenience of your own bar.
Whether that is worth the extra £20.62 per match (£495/24 games) is for the individual to decide.
