We bought through the other company. (I think its the one being blanked out) Everything went well. We had seen HER website linked to another Disney website and signed up for her email newsletter service on DH's email account. When we got ready to buy, she had a 100 point Boardwalk listed that was right down our alley.
We asked about timeframes of when we should close, pass ROFR, etc., because we'd never done anything like this, and it all went as they said.
We called some at the appropriate times, but it didn't seem out of the ordinary for a real estate closing, and sooooo much easier than closing on a house!
I admit, sending a big check to something you'd only seen on a website was scary!

I would have said the same thing about TSS.
We started the process in December of '05 and closed in mid-January of '06. We had to pay maintenance fees for the year with closing costs, and don't know if that was customary for that time of year or not. It seemed to make sense.
