Even though I fear being seen as a curmudgeon, I'm going to tell you my opinion. Please don't bring that scooter. There is nothing worse than having to dodge kids on wheels at the end of a long and tiring day. The difference between scooters and the rented vehicles? BRAKES!
It only takes one not well supervised child on skates or a scooter to make it miserable for others. This is not implying that yours would be, but I have seen too many parents whose thought seems to be that they are on vacation, so they are vacationing from being a parent too.
There is plenty for DD to do without a scooter.
