Using my own experience almost every corporate rate I have used includes breakfast and if it doesn't there is no issue with charging breakfast to expense, therefore arriving a bit later in the evening when drinks have finished or are near to finishing the drinks voucher would be more appealing.

Not everyone wants to sit in a lounge either so again the drinks voucher is more appealing as they can use it at their own leisure rather than between 6pm & 8pm or whatever the times are.

Then there is the question of what will happen to these lounges once they start letting top tier in? There are plenty out there that are "Cosy" as it is. You only need to look at some of Hiltons lounges to see that they are overcrowded and resemble feeding time at the zoo. This can also put people off as the peaceful lounge is now anything but peaceful and you are having to share tables or better still - stand.

The voucher is also good for points according to the first post in the thread so there will also be some people who will take the points even if it is a small amount if they are building up their balance for a big trip etc.

Leisure stays are completely different of course and I would agree that drinks and breakfast make a considerable saving. There is many a time I have booked a Hilton instead of IHG hotel because it works out cheaper by the time the breakfast costs have been factored in.

I wouldn't write off the uptake level of the voucher, it's probably higher than some think it will be.
