'Wow! I don't know you, but I know you're amazing! 5 kids! 4 boys! A set of Twins! A 2 year old! And going to Disney! (I have 4 sisters older than me, including a set of twins. So I know you must be super-parents!)
It didn't cost that much for Behind the Seeds. If you can manage the kids for an hour (of course you can, but I mean it's different at Disney, because that's a whole diff ball game from any other place.... especially with 4 boys... even more so when there are twins!), why don't you let hubbie go on that one by himself?!
Maybe ye can go on the ride that goes thru that same area? Nice slow moving boat.. And there's one of those Kidcot activity centres nearby.
I did it and enjoyed it. But I was with family that day, and knew nobody else would be too interested, so I went on my own.
