Hello! Any recs for a venue to host a sushi making class (bringing in host) + drinks for a group of 30 in Huntington Beach, CA?

Good Morning! Have any of your planned /executed private group events in any of the Walt Disney World (Orlando) parks before? I've got a dinner and buyout of 2 attractions planned in Epcot for 600 (Contract signed and site visit complete). They've been great so far but since this is my first time working an event in their park and with their catering team I don't know what I don't know and would appreciate any tips of things I _should_ know that they may not tell you in advance. If you've thought "if only I knew that sooner" - I want to know! Would love to connect with anyone who can offer advice. Thank you!
