It has to be option a)
I would be gutted if I had clickfested intime, but my choice of day one had gone and I was not allocated the other day one if available.
And if it is not an option for anyone, then they can always put it on the seat exchange as you say.
I would say this as well, especially as if they were given the option I would expect most people would accept the alternative day and then try and "find a way" to make it.
Having said that I don"t think having 50 seats going through the seat exchange board would be a good idea - so if there are too many I can see how administratively the other option would be preferable.
I agree.
Is there an option "not to choose a day"?
Because if you HAVE to choose a day, it does not mean that you can"t make the other day - it"s just that you HAD to choose one.
If you qualify by the clickfest i.e. one of the first 220ish to have completed the ordeal, you should be entered.
As Des said there is plenty of time to try and make arrangements to make the other day. If alas you can"t then I am sure there will be 1 or 2 that would be interested in buying your seat.
