Hi! I can't change them, but I wondered how the second to last row in the center rear balcony is? I was told it was a good location, but now I'm not so sure. I expect we will need our binoculars, but who knows?
RE: Billy Elliot seating -- Those seats should do you wonderfully. The Imperial isn't *that* big, and in reality, all seats are good seats. Your view should be fine!
melodyrose- I have tickets for row G of the rear balcony for Dec. 22nd, when are you going? If you go before then, could you let me know how your seats are?
