Off the back of Nicks thread, Alton towers is shutting in a few weeks, so probably not worth considering this year.  HOWEVER, who would be interested in going next year once it's re-opened?  Could get a discount for mass booking I'm positive.  If you like Theme Parks give a shout out and I'll make a list.  Then sort out dates next year, although provisionally might look at March.
