Dragging kids through the parts of a theme park they don't want to be in is selfish, and as I said previously, it's perfectly OK for 7 year old DD to learn that sometimes you face disappointments in life.
I totally disagree with your example- It's part of being a family to do things that aren't your choice but someone elses. A child over about 5 should be able to deal with that if you don't want to raise selfish children who think "we only do what I want if I'm along."
It's perfectly Ok for a seven year old to learn that life has disappointments AND that sometimes you do what someone else chooses because you are a good sport and they are important too.
Adult trips to WDW selfish!
Maybe there would be less relationship strife in the world if more people went to WDW without their kids! I love my kids, but I need to nurture my marriage, too! And I'll vacation any darn place I want to...kids need to learn that the universe doesn't revolve around them!
Your kids will grow up one day and will want to take trips on their own. Trust me...they won't feel guilty at all! Enjoy!
thanks for asking.
