We are going on our first cruise this fall. We have 3 young children under 5 and decided to ask my mother to come along to help with the kids. We payed for her. My father is not the kid loving type. I mean he loves our kids, but doesn't care to spend days at a time with them. We didn't ask him to go for this reason and the cost, of course. He has made a few comments about us not asking him to go, but we knew he wouldn't enjoy chasing after kids. Has anyone asked just one grandparent to tag along? Should we have invited him too?
