I think it would work for anyone, likely according to availability. I don't think they asked if we were staying at the resort and they had lots of times open, I think because it's so new. We did it right away 10 AM, she had only 2 or 3 others booked through mid day.

We were lucky enough to be able to spend 4 days among "the rich people" - only because it was the only place left with free dining and the $'s worked out... (they eat a lot!) It was beautiful and interesting to see some of the "suits" with blackberries (AKA crackberries) in hand with the kids zooming around their feet.
I'm hoping it will be more widely available, I don't expect to get to the GF again... unless... an anniversay?? He owes me for the coming 25th??
