At that age we brought - we drive to WDW tho it’s 20 hrs - every article of Disney apparel that the kid fit into. Fewer t-shirts bought
We also brought every plush Disney character the kid owned. Prior to the trip we discussed character goals - we had Tramp but no Lady, she’s on the list. x 3. We’re only looking for 3 plushies this trip. Fewer plushies bought. *
At our resort the plushies lived on the kid’s bed. Sometimes mousekeeping rearranged plushies - extra fun. We did not mention ahead of time that this could happen.
Each evening we decided on a “friend” to go to the park in the morning. *see above. This friend got to ride rides and hug characters.
Each kid also had a daily envelope with money - five to ten dollars, depending on how much they saved/earned. Daily money could be saved toward more expensive stuff.
Bringing our already owned Disney stuff saved money and helped the kid manage their money. This worked for boys or girls.
We also always brought a bunch of glow stuff from our local Dollar General.
And did pin trading. Every day different pins would be brought to the park - to wear (show off) and pins to trade.
Through 2019 we did goodie bags for everyone in our group with this trip’s t-shirt, a bunch of lame pins for trading, glow stuff, I don’t even recall what all.
