Thanks for sharing the information, R2. Very useful! However, I find it odd that one has to book a suite to be able to get a voucher for a drink (one drink, really?) and snacks. It should be offered to all diamond and platinum members automatically. And why can't they have a table service at the lounge? I have never seen the lounge crowded.

Edit: Hilton Tallinn offers all lounge services but the lounge has been moved temporarily to the second floor, in a private area at restaurant.
