IMO it has to be a case of first in best dressed. The logistics of holding those seats is a problem - how long for? if they're not taken up are you offering better seats to the public than members who jumped on the presale? Does it stop people around them bringing someone extra? In your situation from what I can understand you wouldn't be getting your usual seats anyway with those extra people.Okay. Who should get them?
I get what you're saying and the impact on some people personally sucks but I'm not sure it's practical to do things differently.
