It took me nearly a week to get a reservation on POINTS. If you're paying $$, you can do it online or call in directly to make the reservation.

If you're doing it on points, they TRANSFER your call to an ANSWERING machine whereby you leave your call back number.
I got a call about 3 days later and I was able to book then.

Having read about the extreme service, whether they are super good or super bad, with none in the middle, I was feeling skittish and decided to cancel my reservation.
I called in, once again, and asked to cancel the reservation, which was prompt...I've received a cancellation confirmation email right away.
However, it's been 2 days already, with calling in through the reps at Hyatt and on Twitter, and they can't get a hold of a Miraval agent that will confirm my cancellation as the return of my points must be done manually.

So my 130,000 points for the 2 nights for 2 people are in limbo....until someone at Miraval wakes up and does their job....

Are they stuck back in the 80s??
I hope they don't ask me to fax them something...

Anyways, if you do speculative reservations, just beware, it's not easy at all...
