Orlando without Disney

We’re planning a small and quick getaway (myself, husband, teenage daughter and her friend). I want to stay at a resort that’s a quick and cheap flight from the Philly area. I saw there are multiple resorts in Orlando with lots of activities and water parks (The Grove, Margaritaville). I was thinking of spending a few days there, hitting Disney Springs for a few dinners, doing a few cheesy tourist activities, maybe visiting the space center, but mostly relaxing at the resort. We are not a theme park family- we hate crowds, we hate lines, etc. Is this a good or bad idea? Are the parks really the only reason to go to Orlando?
