Jim, I would certainly recommend Bluebonnet Ridge in Terrell. It is on I-20, not I-30, but easy to get to from that direction. You could take State Hwy 34 from Greenville, Tx south to Terrell to I-20, then it's just a couple exits east on I-20.
We used to live in Terrell, it's about 35 miles from the heart of downtown Dallas. That might take an hour to get there with traffic, just so you know.
