Used them twice without any problems. They're owned by the PCC people (Ochoa brothers) you're buying your timeshare from, if you're buying on eBay. I think they handle closing on all their in-house sales.
All my paperwork was correct on the first try, but it still took awhile for things to close - like four to five months - but it may have been because the timeshares were in Hawaii. Be patient, and make sure you save all your documents: After the most recent closing, Wyndham tried to ding me for maintenance fees I'd paid up front to Title Outlet. I had to contact Title Outlet to get them to prove to Wyndham those fees had been paid. Took several extra days, but eventually things got straightened out. I don't know if that issue was a problem with Title Outlet, but am more likely to suspect Wyndham dropped the ball.
They were/are professional and responsive. Just stay on top of them as far as timing. Make sure you ask for a copy of the deed the day they receive it from the "seller" and follow-up as to when they send to recorder etc.
They will "mail" most docs as opposed to overnight which can add a lot of time ("checks in the mail"...) and you cannot confirm when sent/received. This may also cause further delays in recording etc. and they may "fudge" when they receive/send deed for recording, etc. I would tell them you will pay for overnight for deeds etc and require they send you tracking numbers. This would have saved me weeks of time.
