I think they need something more unique than Alpina.
This park is in just about one of the most convenient locations you can get. It has an awesome drop tower, a great water coaster, one of the most respected kids areas in the UK, a fantastic new hotel - and the park itself is in nice surroundings as well. It has A LOT going for it. What it needs is some investment for an absolute top drawer coaster not another off the shelf coaster.
They haven't got Alton Towers money to spend unfortunately but that's exactly what they need. I do wonder whether they're saving up for something and just keep building sensible little attractions, the Air Race, Thomas Land, the hotel etc until they unleash something a bit special like Shockwave was back when it was built.
If you think about it, like for like, they've done well. Stormforce10 made a big impact, Shockwave was awesome (comparatively) when built, Apocalypse is still probably the UKs most intimidating drop ride, Ben10 is a brilliant family coaster (not ridden it) - really G Force was the parks main mistake (I cannot believe I still haven't ridden it, I live half an hour away, and that says it all).
I want that ride that's going to make me put my hand in my pocket for a season pass there. Footfall is NOT a problem, location is damn near perfect, really Drayton is a "sleeping giant" that needs to wake and return to the halcyon days and reach it's potential as a park.
