I'm Italian, my family is Italian, and DH2B's little old grandma is as Italian as it gets (she's tooo cute!!) and we like Carabba's. We went there for DH2B's birthday a few weeks ago... Mmmmm... I want Carabbas for lunch now!
I just checked on a map and there's one 5 mi from Disney in Kissimmee.
i would recommend portabello yacht club at downtown disney pleasure island area (no admission cost) has italian. this would be easy for most guests to get to too since they could take the dtd bus from their disney resort. click here to view the menu: http://www.allearsnet.com/menu/menu_pyc.htm
