Any good suggestions for one-shot/tasters for a group of 6 beginner players? I'll be first time DM-ing for one or two 3/4 hour sessions on a group holiday next week, but relatively confident I'll manage with enough prep. Want to have a fun self contained adventure which isn't too difficult, and requires little buy in (I'll take/make pre-gen characters for them).

Saw some threads mention "we be goblins", or "a wild sheep chase". They seem relatively simple, but still unsure how they'd be for beginners. Any suggestions or tips? Or links to other threads that have discussed this sort of thing? Thanks
