The conference organizers said on the event's site that it's just too slow and pricey to accept at the last minute. It seems as though that on-chain fees have risen to $30 to $60 per transaction.

Keynote Events went on to say that it has and "always will" accept cryptocurrencies for their conferences up to 14 days before the event.

The attendees of an upcoming Bitcoin conference have been told they won't be able to use the cryptocurrency to buy tickets.
