Quoted from ForceFlow:

That reminds me--it was nearly impossible to hear any announcements in the free play room. From the middle of the room, I could sort of hear that there was something being broadcast over the speakers, but by the time I made my way over to the speakers to hear what it was, the announcement was over.
So--a few suggestions: better sound coverage, louder volume on the speakers, and/or repeat the announcement a second time for folks like me who tried to get to a speaker to hear what was being said.

Quoted from Daniml:

I spoke to several attendees that felt there were no "show deals" to be had in the Vendor Hall. Some said they'd get better deals on-line even after paying for shipping. Anyone else feel this way as well?
