The hotels listed in the link above have room blocks in place for World of Wrestling participants. To get a room, or multiple rooms, at the hotel of your choice you can use the Reserve a Room feature.

You can also call CSTT Sports Travel 1-866-861-8326 and reserve a room over the phone. Just say you are looking for a room for the Kickoff Classic or Tulsa Nationals, and anyone can help you.
Once your room is reserved, using the online system or by calling CSTT, you will receive a confirmation email.
There are no charges to credit cards, and rooms can easily be cancelled at a later date.
If you have questions about any of the hotels, CSTT Sports Travel can answer those as well
