I need a Minecraft network hub/lobby built I need it to be spacious enough for large traffic spikes, around 300 players at once. Instead of one spawn point, I want 3 separate spawn areas/platforms around the lobby. I can handle the teleport logic, I just need the build to include the 3 spawn locations. The lobby only needs space for 1 NPC/server selector, but it should be easy to reach from all 3 spawn areas. I would like jump pads to help players get to the NPC quickly. Main features: - 3 separate spawn areas/platforms - 1 NPC/server selector area - A very cool parkour course as the main attraction - Parkour leaderboard area - Jump pads - Viewing spots for watching parkour - AFK/hangout spots - Void-safe design - Small open event area for holidays/special events Simple polished build
