Both times have stayed at the Novotel in Brentford have received Drinks Vouchers, anything bar cocktails and champagne/sparkling wine included

Ibis in Leeds I'd checked in online before hand and drinks voucher was supplied with room key, choice of anything from the bar (and for an ibis they had a wide and varied selection!)

Stayed at the Pullman Albert Park (Melbourne) last week, as an Silver I got 2x welcome drink vouchers for anything at the bar.

Also received a free bottle of water in the room (well somedays)

I find Accor status to be an little weird, of an 7 Night stay at the Pullman I had requafiled for another year of silver, and now 3000points off gold!

Vietnam -

Sofitel Plaza - 2 drink vouchers provided for lobby bar with a specific menu for the welcome drink consisting or cocktails, beer, wine and soft drinks.

Sofitel Metropole - welcome drink in the form of a letter waiting in room upon arrival but seemed to be offered to everyone staying there rather than just Plats. Limited choice of drinks.

Pullman Hanoi - 1 welcome drink given but only when asked. It was only for one person which I felt was mean so I insisted that it should be for 2 people and eventually they gave another one. Choice of wine, beer, soft drinks.

Mercure Da Nang - no welcome drink voucher provided and I didn't ask.

I don't have 90 posts so can't edit the Wiki but:

Ibis Styles Leyton (London): nothing offered, and I wasn't fussed, hotel is a bit of a dump.
Ibis Friedrichshafen Airport: voucher offered after requesting and receptionist checked a quick reference card of benefits by level. Able to use for a large wheat beer.
Ibis Amsterdam Airport: room key and vouchers prepared before arrival: booked two twin rooms and vouchers were good for 4 drinks. Awesome. All 4 used for large beers in the restaurant. All staff seemed knowledgeable and relaxed about their use.

It cannot: you must have 90 posts. Which is about 70 more for me!:(
