I would say my children are spoiled but not rotten. Owning DVc has definately increased the times per year we do travel to Disney. HOWEVER even when money was tight( Newly married, buying a house) I still took my dd almost 18 every year no matter what. I do notice they ask all the time can we go now, can we go now? But if I stop and think about it, My dd would only go once a year and she too asked all the time too. I think it's more a reflection of being little and not having a concept of time VS expecting to be taken.
My DVC was a gift from my brother. He wanted his neices and nephews to make sure they went every year. So in 1998? He gave me DVC for the kids and myself. So I continually remind my children, That you get to go and stay at the Boardwalk because Uncle Daniel bought it for you. That is very understood and I think appreciated.
Most of entire family is Disney obssessed and several of us are DVC owners, We always go together, so it is a family time situation. That is the value in it for me. My kids would be devasted if everyone wasn't there.
That being said My inlaws and Dh hate Disney. they are of the opinion that once you have been once. You need not ever go again. They are furious that I go so frequently. When I first had DVC they made a big presentation of an envelope full of cash( spending money for the week)

Now they have not done that inyears. No matter how many times, I try to explain, that I am not paying Lodging everytime I go, They simply do not get it.It's unfortunate because I think if they went just once they would love it. They have never been, My MIL won't fly, and he won't leave her so thats that. They are ultra negative about it. I just have learned to smile and ignore it.
And by the way ROADTRIPPER $12 cable! I am impressed.
