Hors D'oeuvre recipes needed

I’ve been tasked with providing the hors d’oerves for a NYE sit down dinner party for 12 guests. The hors d’oerves will be traveling about an hour to get there. No oven access on site. They most likely will be served shortly after arrival although should be able to withstand sitting out for a couple of hours both indoors and out (in Florida). Suggestions and recipes needed, please!
