You could visit both Historic Downtown Kissimmee (not Old Town) and Lake Toho at the same time. Go down the 192 east, past WalMart. When you get to the junction with Orange Blossom Trail, turn right, through the 'gate' into downtown. Park up and have a browse around the shops, they are quite unusual and olde worlde. Then drive on a couple of more blocks (Oak Street I think) and turn left. You will come to Lake Toho. There are covered picnic areas there with BBQs if you want to take some food. I am sure that somewhere along the lakefront stretch there are swings. It is quite an enjoyable way to pass a couple of hours or so. Chloe
