I used to go to My Three Sons as a kid myself, now I take my children. I was recently there on a Saturday. Personally, I thought the renovations would be more impressive. Yes, they added many new arcade games, but they still have a lot of the old ones around taking up space. It seemed they were understaffed the day that I took the kids...We've always been pretty satisfied throughout the years. But this particular time was a bit different. For starters, I think they were understaffed the day we went (Saturday). My kid got hurt in the bouncy house, his nose was bleeding, I sent my oldest to get paper towels from a staff member. He came back with no paper towels saying the staff was tending to the birthday party. It seemed that the birthday party had 20+ kids by the way. So I had to use the wipes I had taken, when his nosebleed calmed down, we went to the bathroom. So no staff member noticed there was a nosebleed at the bounce house.
I felt bad for the young man trying to be in 3 places at once. When it was time to redeem our prize points, there he was all alone trying to tend to about 6 families, kids were shouting out to him trying to get his attention. He finally asked a staff member walking around to send for backup. I was going to ask for a manager but it was just too crazy so we decided to leave.
So my kind suggestion would be to remove the old arcade games and prepare more staff for busy days.
