Well, Baldwin Park is fantastic so I am sure you will love it there! The community also has plenty of things to do within a short distance so it is possible your parents would love to stay close and live in Baldwin Park too. You can even find homes with garage apartments if you want to keep them really, really close. If they like social events, try Winter Park near downtown. Farmers market on the weekend, shopping, dining, plus maybe your mom could volunteer at Rollins College or a local church. Audubon Park is also nearby and prices there are reasonable, the Leu Gardens would be a great place to volunteer and visit. If they want to go a bit further away, try College Park on the west side of Orlando or Lake Nona and Avalon Park to the East. Also, can't help but mention Celebration. Practically and 'sister town' to Baldwin Park. I lived near my parents in Celebration for over 2 years and we all loved it! Plenty of activities, close to Disney, great 'community feeling'
I hope that helps broaden the search. If you are looking for 55+ only, then of course that is a different story, but there a several in a few of the areas I mentioned. If you would like, I can search more specifically and provide a list according to their criteria.
Best of luck to you on your move and also to your parents.
