SIYB has implemented a Stay to Play policy for all of our tournaments.  As a condition of acceptance to our tournaments, all traveling teams need to utilize official Tournament hotels available through the Event Connect by RoomRoster software. Out of town teams (teams more than 80 miles from Spokane) will be required to book through the Event Connect by RoomRoster Software.

To support our organization’s goal of creating the best tournament experience for every team manager, coach and family, we have implemented new tournament management software to manage the following:

  • Tournament Registration
  • Accommodation Management
  • ALL traveling participants are required to secure accommodations within this software
  • Discounted rates at official tournament hotels have been pre-negotiated
  • For those looking for a specific hotel that is not on our official list, the system will make available all remaining hotel inventory at current online rates.
  • Player & Team Questionnaire – i.e. Liability waiver
  • Communication and Updates
  • Scoring and Scheduling
  • Venue directions and details
  • Fully integrated tournament app
  • Available for download to any mobile device or tablet
  • Personalized for each participant and team to include:
  • Integrated hotel reservation details
  • Team schedule, standings and scoring updates
  • Venue directions
  • Real-time tournament announcements
  • Personal calendar updates

Please do not hesitate to contact our RoomRoster Support Team at 1-888-723-2064 or at should you have any questions or require any assistance during the hotel booking process.
