I have a Double/Double at the Sheraton City Centre 8/1-8/5. Looking to trade for a King room anywhere downtown. It's just 2 of us so figured I'd see if anyone who had more people would prefer the extra bed over floor space. Ping me if interested. 

I don't have one but last year my fiance and I were in the same situation. We just asked if we could get a king at check in and the hotel was able to. I just wanted to let you know because trading is tricky this year.

Can rooms be traded within the block?

We've been able to in previous years. Has that changed? 

It has.  Per the Housing Terms of Service - 

• 10.Room Assignment Management. Room assignments are unique and personal to the Gen Con account holder who purchased the badge and requested the assignment. Room assignments cannot be transferred, traded, or otherwise re-assigned among Gen Con accounts, and room assignments connected to one Gen Con account will remain associated with the account until housing registration closes or the room assignment is cancelled.
  

Alrighty then. That stinks. Thank you!

That policy only applies while GenCon holds the reservation.

Nothing will stop you from trading after the reservation has been sent to the hotels and they have the reservation under your name.

Ah I see. Thank you for clarifying :) 

I may consider your offer after the housing block closes

I was able to snag a King at Columbia Club. Thank you for the offers, everyone!

I may be in this same situation where I would prefer to stay in a Marriott property. We have a 3 bed suite at the Hilton and may not need the third bed. We will know in the next couple of weeks. If anyone is interested in trading after the rooms are released let me know.
