Multi Year Platinum and now Diamond.
Lower end hotels ( Ibis etc ) normally provide just water, however sometimes they go the extra mile on the "amenity"
Sofitel etc mostly do provide something. Maybe just a selection of fruit ( that I don't want - its in my profile ) or some leftover breakfast or lounge items. Sometimes even cling filmed.
Have stayed at top rated hotels and been underwhelmed, and lower grade and been pleasantly surprised. There is a thread here for the welcome amenity for Gold plus members.
Over the years the "average" has been water, or some fruit ( mostly apples )
The surprising observation I have made is that on staying in some hotels I either get "more" or "less" than other posters on FT.
APAC normally gives more. France well .... we will not comment !
Its the same with the welcome drinks as well.
You can tell when its a "Accor" hotel or just an "Accor doing the least"
TBH I would complain depending on room rate
