I apologize if this was already discussed (i did search), but are the dates for GaryCon X (2018) known?
I just made a reservation for Gary Con X at Grand Geneva. I believe the entire hotel is blocked off for people attending Gary Con X which means only people going to Gary Con can get a room. There are still rooms available. Call them at 1-800-558-3417 and tell them you want a room for Gary Con.
Got one of the block rooms but couldn't get one reserved to arrive on the 6th. Wish I had acted faster for a suite.
Tried booking online, no luck, then tried calling about an hour ago and was on hold so long that their system put me to voicemail. Just called back and made reservations for a room, so seems like they are busy taking reservations but are very busy.
