It seems I remember this very same discussion on these forums last year for the month after Transformers opened, ie. parks not as crowded as expected, merchandise & food sales under expectations etc., but then the Universal execs publicly stated that Transformers had increased Studios attendance by 25%. Some of this staffing may just be normal adjustments after the expected chaos of opening week and a different crowd flow than before expansion. I fully expect a huge spike in attendance. Two things in particular, 1)Diagon, London & Hogwarts have huge capacity, and if rest of the Studios appears to be normal than that's a lot of extra attendance. 2) Potter now has two locations, so if they're both fairly busy, that's a heck of a lot of people occupied by Potter.....If both parks are fairly busy, that's a big plus since Studios attendance was flat or slow when Hogsmeade opened, so you really only had one busy park in 2010.
