I just stayed in both Estoril and in Porto, and both offered the "Club Experience" ...
I appreciate it ... free breakfast and some of the other Club perks like pressing. The evening cocktails/canapes were less than what you usually have in a Club. 4 appetizers. At least in both cases they gave me seconds. And both had a good selection of Portuguese wines. And they offered this later than the actual Club in Lisbon, which closed the Club food selection at 7:01 pm and wouldn't even serve me a drink ... the only thing on time in Portugal, and at the wrong hour.
Though not quite like having a Club Lounge, I would definitely hope that ICs without a Club (yes you, IC Tokyo Strings, IC Times Square, Willard, IC Vendome Beirut, Toronto Yorkville, LA Century City, and IC New Orleans which once had a Club) all adopt the "Club Experience."
I note the Chicago IC this year has been offering free breakfast and evening drink vouchers and coffee vouchers, a "Club Experience Lite."
I haven't been in the Amstel in over a year; the lack of a Club for such a high-end IC was always awkward; this would be a nice perk.
