I currently live in Spring Hill and can tell you that it is NOT an area that you want to live... especially if you have children. I'll address this issue in a moment but wanted to suggest several options for living within 30-45 minutes of Disney
1) Clermont
2) Winter Garden
3) Winter Park
4) Celebration if you can live with the covenants
As for anyone who is thinking of living in Spring Hill- Hernando County has the 14% unemployment rate with the primary industries being fishing and retail. Many of the retail shopping center projects that are in mid-construction are now being abandoned completely and like most places, are witnessing entire shopping centers closing all together. On a positive note, due to the insanely high forclosure rate (over 2000 properties in forclosure) you can get a newer model home for next to nothing... then again, with 2 more homeowner insurers pulling out of the business here in Florida, you will make up the cost difference by way of high property taxes and crazy-high insurance rates (auto and home- remember, not only are you in Florida BUT you are now living on the coast) Also, the highschool drop out rate is now 26%. As soon as my lease is up in November, I will be relocating closer to Tampa.
However, there are some wonderful things about where I live:
It takes me 1 hour 10 minutes to get to Disney

and 1 hour to get to the Tampa airport. Most of the people here are elderly so the violent crime rate is uber-low. Most of the people here are elderly so it's relatively quiet. Most of the people here are elderly so there are 4 hospitals within 10 square miles

Did i mention it only takes me an hour 10 min to get to Disney???
