Looking for a quickstart that is also a one shot

I am going to the beech with the family this fall. they have asked me to run D&D. But they have never played D&D and honestly I think the most we will play at the beech is 1-3 four hour sessions.

I see some decent quick starts but most are for groups committed to a longer 5-10 session thing. 

I am looking for recomendations

There are some super tiny things, such as https://www.dndbeyond.com/sources/dnd/bqdd/borderlands-quest-dagger-danger . How much you can actually get through in 1-3 sessions with complete novices is heavily dependent on the group.

I have low expectations of 50% of them lol thanks

Worth taking a look at Peril in Pinebrook. It was released a couple of years ago as a one shot people who play could run at Thanksgiving with their families who had never played. It’s about two hours to run but the best thing is it comes with abbreviated character sheets that are only about half a page and only use a d20 and a d6 so greatly cuts down on the amount of confusing things to give new players
