Since the OP asked if anyone on the board actually lived here, and was seeking an opinion - I have some observations from "Inside the Bubble".
And I'll address some of the earlier comments and questions as best I can.
Celebration is like most places, it's as good or bad as you choose to make it. And it has it's own built in good and bad as well.
Lawn decorations, I don't know about pink flamingos, but Celebration really gets decked out in a major way for Christmas and Halloween, and in some areas Easter. It's encouraged actually. No problem either with flags, door wreaths, etc, etc.
Look alike houses - not really. the restrictive covenants prevent same design/color homes from being too close. Are the houses too close together? Yes, find me a development in the last ten years where they aren't.
Expensive - certainly. But there's been a real estate bubble nationwide. A realtor neighbor tells me that something like 12% of Celebration homes are worth more than $1,000,000.
Stepford. No. If it were Stepford, it would be perfect and this place isn't even close. Besides, the Stepford joke became stale and yawn inducing about 8 years ago.
The Bucs take over the entire hotel every August. If any of the Braves are here, they're doing it as individuals, not as a team. I've been told they stay on Dis property, but I don't know.
With the exception of restaurants and the theater, downtown is not for residents, except that it's a great place to hang out when the weather's nice. No grocery, no drug store, no hardware store. Frankly, the merchants survive because of tourists, which is a shame.
Town business and common area issues are handled by a confusing collections of boards, committees and companies. To address a town issue is to deal with a dysfunctional beaurocracy that is largely inept and slow to act.
The alligator sign is in the lake because there are alligators in the lakes. I killed a coral snake in my back yard last month. We spray every night for mosquitos because they are fierce. Welcome to the tropics.
Celebrities? Don't know of even one - which doesn't mean they aren't here. Bill Gates looked here once, as did Julia Roberts (allegedly).
Random factoid - we go to PI for a movie every Halloween because buying candy would break me. My neighbor had 1200 trick or treaters last year. People come in from far and wide, and they are welcomed.
Ok, thanks for letting me ramble a little too much.
I love this place - wouldn't live anywhere else right now.
