Wow. That's quite a lot of value.
When I was there in June, we also used the spa, and I agree, it is a fabulous spa. I also had the 45 minute pedicure cert, and they agreed to let me apply the value of that treatment against a massage treatment instead.
We LOVED Castello. Everything we ordered there was just fabulous. I was surprised at how small it is, which I guess explains why reservations are so important. I think I reserved about 3 months in advance and still couldn't get my preferred seating time.
They were slow to redeem some of my certs. We stayed at the 3 Fairmonts in the Rockies on the trip. The CLL certs posted almost immediately. The redemptions at the Springs seemed to take a week or so. The dining certs posted quickly, but I think it took at least a week for the upgrade cert to post. It's at the JPL where after about 8 weeks my upgrade cert has yet to post.
