UPDATE:
-> see @PatrickD & my post below:
just in case we need 3 dm’s, here was the original post:
In case there will be 3 tables again,
I will dm the (low) T2 oriental-themed pirate-treasure hunt Shore of Dreams 
If there will be (only) two tables, I could dm the Pudding Faire for T1 (again),
for those who have not played it already. 
If all breaks down, I could dm my old D&D 5 tournament-adventure
(so it does include scoring for bragging-rights … @H, @KauraKuitu, @GJsoft & @darthkiwi score is unreached since 2015)
DVNGEON INVICTVS, an ancient graeco-roman-themed dungeon-crawl,
but since this won’t be AL-legal and uses pre-generated characters, I would suggest (Will-Save DC 19) using one of the two options mentioned above.
P.S.: max. of 5 players at my table, please
