Are large extended-family gatherings welcome at splash pads?

Splash pad culture in many American immigrant and traditional communities centers on the extended-family weekend gathering: grandparents, parents, aunts and uncles, cousins, and friends-as-family, sometimes 20-30 people, with grills, music, and an all-day picnic. This is welcome at virtually every public splash pad. Best practices: reserve a picnic shelter if your park allows it (many do for $25-100); arrive early on summer Saturdays before 10 AM to claim a corner of the lawn; bring multiple coolers and shade structures (pop-up tents up to 10x10 are usually fine); supervise as a group with a 'who's watching whom' rotation rather than assuming someone is; respect the splash pad surface itself by keeping food, blankets, and large items off it; and pack out absolutely everything including stray cups and napkins. Etiquette: do not claim every shaded bench, do not blast music loud enough for the next zone over to hear, and accept that other families also need access to jets. Cleanup is the cultural test — leave the area cleaner than you found it.
