While I'm all for transparency at qualification criteria, another level at the Ambassador program doesn't make much sense for me.
There already are leisure stay rates of weekend and long stay variety. Along with the regular AMB, the only difference would be a one level upgrade (kind of a wash at some leisure properties with view/floor distinguishing categories) + benefits like mini bar etc. Not really big of a deal if you book to get club access for example. All for a lower price - where's the deal for IHG ?
I'd very much rather see a guaranteed club access/breakfast and extension of the benefits to award stays for the regular RA program. Maybe also throwing a bone for the occasional other IHG brand stayer, with some benefits extending in that territory.
