My understanding is RESORT FEE alike fees. For example, NYC Marriot Marquis calls its own Resort Fee as Destination Fee. Several Kimpton hotels have these resort fee called Amenity Fee.

That is why my speculation is that one day Ambassador programme will be extended to Kimpton, because so far most IC hotel that has Resort Fee actually called it Resort Fee. But some Kimpton hotels used words like Destination Fee or Amenity Fee.

Also that is reason that I thought the new benefits for Ambassador is a combination or better, a compromise of current Ambassador programme and Kimpton Karma/Inner Circle so that Kimpton hotel owners can easily get on board. But I am not familiar with Kimpton Inner Circle programme and need someone from the programme to tell me more in order for me to further affirm my speculation.
