I'd have my wedding in the closed season so no members of the public are watching, I like my privacy! I'd have the my wedding ceremony the in centre of the castle, followed by a horse and carriage ride through the gardens, down woodland walk and in to the Alton Towers Hotel gardens for cocktails etc. Then wedding reception would be in the conference centre with catering being a carvery. After wedding reception and speech's there will be 1 hour ride time on Air, to express our love that flys around in the Air :-)... Then a big party will be back in the conference centre till 2am in the morning with some Creamfields DJs. :-)
I don't believe the resort offer on site wedding ceremonies anymore and you certainly wouldn't get a horse and cart down woodland walk. Good luck affording this too, Air ERT starts at around £1k minimum
He was asking, what would you do IF you could have a wedding at Alton Towers. It was clearly not a serious question, so reality and money isn't an issue.
