The answer to this question depends on the time of day. I have to make it from Milennia (Conroy Road) to Maitland Blvd. everyday around 1pm. If there isn't any traffic it takes me approximately 22 minutes. When there is traffic, tack on an additional 10 minutes.
Lake Mary is another 10 minutes past the Maitland Blvd. exit.
Needless to say I have take I-4. I don't know if I'd be brave enough to tackle this during rush hour. Last week, I was running late and was caught in traffic on I-4 at 4:00pm. It took 30 minutes just to get from John Young Parkway to Lee Road and then it sort of cleared from that point.
There aren't any other alternative routes that I can think of though. I-4 is the most direct route. Anything else would put you out of your way. If it is possible to commute during non-rush hour times, that might help. I-4 is a different road after 9am and before 3pm.
Congrats on the purchase of the new home. I like the Milennia area. I love the mall and the shops around it. It's an up and coming area and Ikea is nearly finished. Plus, there's BJ's. That's where I get my gas for cheap.
