We went to a the second show on Sunday, August 17th ... doors opened at 5PM, show started at 6:30 PM.
Used ART to get there AND back. No issues ... we were staying at the VGC, so used the DLR Transport pickup area. The last bus picked up at the stop near Pirate's Dinner at about 8:30 PM. Bus was not busy on either run ... us and one other family on the way out (they went to Medieval Times) and an additional couple plus the other family and us on the way back.
Got buy-one, get-one free tickets using the VISITCA discount. For basically $35 each (including the ART round-trip fare) it was a great night out. Telephone staff were super friendly and easy to deal with when purchasing tickets.
All of us (2 grandparents, 3 adults, 3 young boys) really enjoyed the show. Yes parts of it were cheesy, but there was definitely some acrobatic skill and interesting special effects on display. Was it Broadway calibre entertainment? Definitely not, but we weren't expecting it to be.
The meal itself was good ... not fantastic, but more than acceptable. Our server was very attentive to everyone in our full section. We didn't purchase any adult beverages or souvenir items, so no comments there. Our family photo actually turned out very well ... not a easy feat with 8 people in the group (and the photographer only took one shot). (We bought it because we actually wanted to, not because we felt like we had too.)
My only complaint was that the pre-show area got a little congested and the pre-show itself was nothing to write home about. Both those issues could be avoided if you were ok with giving up the appetizers (which were tasty) and not arriving early.
