I am feeling kind of mean as a parent right now. I have never given my kids any money at all to spend.

g I guess I feel like I am being nice taking them to Disney! They do have allowance/birthday money of their own saved and they are allowed to buy whatever they want with that (with the exception of candy...DH's rule). DS has $65 saved so far and DD has $55. The 4 year olds both have $20. This is our first trip to WDW (we have been to DL a few times) so I know they have been saving to get something special because it is a new park with new stuff. However, I don't see the need to give them any more then what they have saved themselves. But that is just my opinion with my kids. I think you should give whatever you feel comfortable giving.

Hope you have a great trip.
