I think speculating on benefits and getting wound up is a bit daft at this point.
I've got a confirmation that says the transfer cost is return. So I'll be paying that and if they charge more they can fight Amex once I'm home.
Ultimately, as a new resort they need reviews to bring in the cash customers. So for 12 months I'd imagine they'll do all they can to make things very comfortable for status guests on points. After that, I fully expect redemption space here to be rare as rocking horse sh**.
Time will tell. Chill.
