The CEC years don't last forever (unless you keep having more children

). My 8 and 10 year old DSs have less interest in going than the OP does!
Our younger nephews were staying with us not long ago, and I thought CEC would be a good outing to get everyone out of the house. I had to drag DSs along. They couldn't believe I was making them to go to "that little kids' place." Of course, I remember when they would have gone there everyday if I would have taken them.
Just get an overpriced plastic cup of beer at CEC and deal with it. You're making great memories for your kids.
