I think that this is a great spot, to let them burn off some energy... maybe have a snack and drink... and kinda regroup..
When we have taken our DGS.. we have made Tom Sawyers Island a spot every time we take him, starting at 2 and he will be 5 this month... I always pack his favorite snacks, and grab some drinks, and sit at the tables or rocking chairs, and enjoy the paddle boat going by, he like to stand at the railing, and wave as it goes by... now he like to run over the barrel bridge...
When I was a kid, you could buy ice cream, and other treats, even hot dogs I think... I really feel this is a missed area... and needs just a bit of love...
