Thank you for your generous support of BronyCon. I apologize for the delays in the hotel reservation forms being sent out. You should have received the form last night; please note the comments at the end as there are changes to the badge/swag pickup process for this year.
While Diamond Sponsor badges had sold out some time ago, we tend to wait until closer to the convention to collect this information as sometimes badges are transferred or plans change and the reservations need to be updated. Waiting until closer to the convention usually means fewer registration errors and a smoother check-in experience for you. Your hotel confirmation details will be sent to you once the room assignments are made. Don't worry about a room being available; Diamond Sponsor rooms are part of a reserved block and were guaranteed before 2017 tickets went on sale. Unfortunately, parking at the Hilton is an additional charge.
I hope I've been able to address your questions. Please don't hesitate to contact us if there's anything else we can do for you.
