Yes and no. Attendee housing registration opens in February and typically sells out within a few days. With that said however, hotel rooms do become available in the months and weeks leading up to Gen Con Indy as attendees change their plans, additional rooms are added to the block, etc. You may want to purchase a 4-day badge so you can get into the housing lottery and then if awarded a grant, request a refund of your 4-day badge.
