Rhode Island state finals at the AMP (formerly the Dunkin' Donuts Center) in downtown Providence. Three divisions, both boys and girls, run over a 3-day window in early March. Smaller state means tighter field, but the venue is legitimate — 12,000-plus seats, also home to Friars college basketball.
National Prep Tournament in Fort Walton Beach, Florida takes both high school and post-grad programs. Applications stay open through October 31. If you want a competitive early-March slot without invitation-only barriers, this is the one to apply for.
