Just wanted to chime in and say I know
exactly how you are feeling! My husband just got a transfer within his company to Melbourne, FL and my job is transferring me too! Only we're on our way down the first week in April
We don't have kids though, so that's a little easier! We're looking at moving into an apartment first, then building a house. We just announced it to our family & friends last week. It's so hard to keep all that excitement inside!
Our original plan was to move to the Orlando area (it's closer to family) but then decided that it would be too much traffic and be too busy for us. But I have to agree with others on Windermere. Winter Garden was also on our radar.
I went down in January to look at houses (and to make sure we liked Melbourne before moving there!) and I have to agree with a PP that mentioned to not rely on photos. Make sure you hook up with a good Realtor and physically visit the neighborhoods. I was shocked at some of the houses where I said "that can't be the same house!"
Check out this blog that I stumbled across:
http://therelocatedtourist.com/ It's someone who moved from the midwest to the Orlando area. I think it would be a good resource for you. It's not as helpful for me since I will be moving to outside the Orlando area.
Also, I grew up in Philly, so I think I know what chain you're talking about. If true, my parents will be excited!
