Well, it's another option for amex holders. Cost is high, but the amenities don't look too bad at LAS. The map shows it at the D gates so it looks to be accessible to DL passengers.

Didn't get the promo mailing unfortunately. I have a business delta platinum amex and a regular personal platinum amex.
